MX100

The rapid proliferation of artificial intelligence (AI) across a growing number of hardware applications has driven an unprecedented demand for specialized compute acceleration not met by conventional von Neumann architectures. Among the competing alternatives, one showing the greatest promise is analog in-memory computing (IMC). Unleashing the potential of multi-level Resistive RAM (RRAM) is making the promise more real today than in the past. Leading this development, TetraMem, Inc., a Silicon Valley based startup, is addressing the fundamental challenges holding this solution back. The company’s unique IMC that employs multi-level RRAM technology provides more efficient, low-latency AI processing that meets the growing needs of modern applications in AR/VR, mobile, IoT, and beyond.

Background on the Semiconductor Industry

The semiconductor industry has seen significant advancements over the past few decades, particularly in response to the burgeoning needs of AI and machine learning (ML). Innovations in chip design have pushed the boundaries of performance and efficiency. However, several intrinsic persistent challenges remain, such as the von Neumann bottleneck and memory wall, which limits data transfer rates between the CPU and memory, and the escalating power consumption and thermal management issues associated with advanced node technologies.

In-memory computing (IMC) represents a ground-breaking computing paradigm shift in how data processing is accomplished. Traditional computing architectures separate memory and processing units, resulting in significant data transfer overheads, especially for the data centric AI applications. On the other hand, IMC integrates memory and processing within the same physical location, enabling faster and more efficient data computations with a crossbar array architecture to further eliminate the large quantity of intermediate data from those matrix operations. This approach is particularly beneficial for AI and ML applications, where large-scale data processing and real-time analytics are critical.

Selecting a suitable memory device for IMC is crucial. Traditional memory technologies like SRAM and DRAM are not optimized for in-memory operations due to their device and cell constraints and their volatility idiosyncrasies. RRAM, with its high density, multilevel capability and non-volatility with superior retention, overcomes these challenges with no refresh needed. The working principle of RRAM involves adjusting the resistance level of the memory cell through controlled voltage or current, mimicking the behavior of synapses in the human brain. This capability makes RRAM particularly suited for analog in-memory computing.

TetraMem has focused its efforts on multi-level RRAM (memristor) technology, which offers several advantages over traditional single level cell memory technologies. RRAM’s ability to store multiple bits per cell and perform efficient matrix multiplications in situ makes it an ideal candidate for IMC. This technology addresses many of the limitations of conventional digital computing, such as bandwidth constraints and power inefficiency.

The RRAM programmable circuit element remembers its last stable resistance level. This resistance level can be adjusted by applying voltage or current. Changes in magnitude and direction of voltage and current applied to the element alters its conductance, thus changing its resistivity. Akin to how a human neuron functions, this mechanism has diverse applications: memory, analog neuron, and, at TetraMem, in-memory computing. The operation of an RRAM is driven by ions. With control of the conductive filament size, ion concentration and height, different multi-levels for cell resistance can be precisely achieved.

Data processed in the same physical location as it is stored with minimum intermediate data movement and storage results in low power consumption. Massive parallel computing by crossbar array architecture with device-level grain cores yields high throughput. And computing by physical laws in this way (Ohm’s law and Kirchhoff’s current law) produces low latency. TetraMem’s nonvolatile compute in-memory cell reduces power consumption by orders of magnitude over a conventional digital von Neumann architecture.

Notable Achievements

TetraMem has achieved significant milestones in the development of RRAM technology. Notably, the company has demonstrated an unprecedented device with 11 bits per cell, achieving over 2,000 levels in a single element. This level of precision represents a major breakthrough in memory compute technology.

Recent publications in prestigious journals such as Nature1 and Science2 highlight TetraMem’s innovative approaches. Techniques to improve cell noise performance and to enhance multi-level IMC have been key areas of advancement. For example, TetraMem has developed proprietary algorithms to suppress random telegraph noise, resulting in superior memory retention and endurance characteristics for RRAM cells.

Operation of IMC

TetraMem’s IMC technology utilizes a crossbar architecture, where each cross-point in the array corresponds to a programmable RRAM memory cell. This configuration allows for highly parallel operations, which are essential for neural network computations. During a Vector-Matrix Multiplication (VMM) operation, input activations are applied to the crossbar array, and the resulting computations are collected on the bit lines. This method significantly reduces the need to transfer data between memory and processing units, thereby enhancing computational efficiency.

Real-World Applications

TetraMem’s first evaluation SoC through the commercial fab process, the MX100 chip (see figure) exemplifies the practical applications of its IMC technology. The chip has been demonstrated in various on-chip demos, showcasing its capabilities in real-world scenarios. One notable demo, the Pupil Center Net (PCN), illustrates the chip’s application in AR/VR for face tracking and authentication monitoring in autonomous vehicles.

To facilitate the adoption of its technology, TetraMem provides a comprehensive Software Development Kit (SDK). This SDK enables developers to define edge AI models seamlessly. Furthermore, the integration with Andes Technology Inc.’s NX27V RISC-V CPU with Vector extensions streamlines operations, making      it easier for customers to deploy TetraMem’s solutions in their products.

The TetraMem IMC design is great for matrix multiplication but not as efficient in other functions such as vector or scalar operations. These operations are used frequently in neural networks.  For these functions, Andes provides the flexibility of a CPU plus a vector engine as well as an existing SoC reference design and a mature compiler and library to accelerate our time to market.

TetraMem collaborated with Andes Technology to integrate its IMC technology with Andes’ RISC-V CPU with Vector Extensions. This partnership enhances the overall system performance, providing a robust platform for a variety of AI tasks. The combined solution leverages the strengths of both companies, offering a flexible and high-performance architecture.

Looking ahead, TetraMem is poised to introduce the MX200 chip based on 22nm, which promises even greater performance and efficiency. This chip is designed for edge inference applications, offering low-power, low-latency AI processing. The MX200 is expected to open new market opportunities, particularly in battery-powered AI devices where energy efficiency is paramount.

Conclusion

TetraMem’s advancements in in-memory computing represent a significant leap forward in the field of AI hardware. By addressing the fundamental challenges of conventional computing, TetraMem is paving the way for more efficient and scalable AI solutions. As the company continues to innovate and collaborate with industry leaders like Andes Technology, the future of AI processing looks promising. TetraMem’s solution not only enhances performance but also lowers the barriers to entry for adopting cutting-edge AI technologies.

Samtec Demystifies Signal Integrity for Everyone

As clock speeds go up, voltages go down and data volumes explode the need for fast, reliable and low latency data channels becomes critical in all kinds of applications. Balancing the requirements of low power and high performance requires the mastery of many skills. At the top of many lists is the need for superior signal integrity, or SI. In its most basic form, SI ensures that a signal is transmitted with sufficient quality (or integrity) to allow effective communication. This definition is deceptively simple. Implementing effective SI requires mastery of many disciplines. There are signal integrity experts among us who have spent an entire career learning how to create reliable, efficient signal channels. But what about the rest of us?  It is often difficult to even know where to start. The good news is that Samtec has an extensive set of resources to help. Let’s look at how Samtec demystifies signal integrity for everyone.

The Tools of the Trade

Understanding signal integrity and how to optimize it demands a working knowledge of a vast array of concepts, technologies and metrics. While most of us know what a baud rate and a differential signal are, the concepts of Nyquist frequency, bit error rates, insertion loss and what exactly an eye diagram illustrates may be a less obvious.

The world of frequency domain analysis, S-parameters and electromagnetic compatibility opens a lot of new concepts and analysis regimes as well. The terminology is easy to get lost in, such as evaluating crosstalk through a NEXT or FEXT lens.

The good news is that Samtec, a company that has mastered signal integrity to deliver high performance data channels of all types, also provides a wide range of tools to help us all understand signal integrity – why it’s important, how to measure it and how to optimize it.

If you are unfamiliar with Samtec, you can get a good overview of what the company has to offer on SemiWiki here.

Samtec to the Rescue

A core resource to help navigate the subtleties and semantics of signal integrity is the document referenced at the top of this post. Samtec’s Signal Integrity Handbook provides everything you need to decode what good signal integrity practices look like and why they are so important. A link is coming so you can get your copy. You’ll be glad to have it. Let’s first look at what’s covered in this handbook and touch on some of the other ways Samtec helps its customers achieve the best system performance possible.

The handbook begins by covering the basics – the definition of signal integrity and the differences in dealing with single-ended and differential signals. Key signaling terms such as NRZ and PAM4 are then explained.  We then explore the entire world of frequency domain analysis and the role of S-parameters. Topics such as insertion loss, return loss and crosstalk are covered here.

The basics of time domain analysis are then explored, with a discussion of topics such as impedance, apparent impedance, propagation delay and skew. The various metrics used to characterize channel performance are then covered. This is followed by a discussion of modeling considerations, where topics such as simulation tools and validation are explored.

System analysis is then covered. This is where we learn about eye diagrams. Methods to select appropriate connectors and how to use them are then detailed. The handbook concludes with a discussion of signal integrity for RF systems. 

You will not likely read this handbook cover to cover, although it is quite well organized and easily consumed. Rather, it will become a reference for you as you navigate the challenges of your next system design.

Beyond the Signal Integrity Handbook, Samtec offers a broad set of resources to dig into the many topics associated with signal integrity. These take the form of short videos and informative blogs. There are links to some of these resources embedded in the handbook, which is quite convenient. If you want a quick overview of the Samtec Signal Integrity Group, you can get that in under two minutes with this informative video. If you want broader access to experts and materials, you can find that on Samtec’s Signal Integrity Center of Excellence. If you’ve moved beyond the basics, Samtec also offers its monthly gEEk spEEK webinar series.

To Learn More

At last, here is where you can download your copy of the Samtec Signal Integrity Handbook. Keep it handy when you start your next design. And that’s how Samtec demystifies signal integrity for everyone.

Hot Chips 2024: AI Hype Booms, But Can Nvidia’s Challengers Succeed?

Hot Chips 2024: AI Hype Booms, But Can Nvidia’s Challengers Succeed?

NVLink switch tray top view open black

You don’t know you’re at a peak until you start to descend, and Hot Chips 2024 is proof that AI hype is still climbing among semiconductor vendors. Juggernaut Nvidia, startups, hyperscalers, and major companies presented their AI accelerators (GPUs and neural-processing units—NPUs) and touched on the challenges of software, memory access, power, and networking. As always, microprocessors also made a significant contribution to the conference program.

Nvidia recapitulated Blackwell details, the monster chip introduced earlier this year. Comprising 208 billion transistors on two reticle-limited dice, it can deliver a theoretical maximum of 20 PFLOPS on four-bit floating-point (FP4) data. The castle wall protecting its dominance is Nvidia’s software, and the company discussed its Quasar quantization stack that facilitates FP4 use and reminded the audience of its 400-plus Cuda-X libraries.

The software barrier for inference is lower. Seeking to bypass it altogether—as well as to offer AI processing in an easier-to-consume chunk than a whole system—AI challengers such as Cerebras and SambaNova provide API access to cloud-based NPUs. Cerebras is unusual in operating multiple data centers, and both companies also offer the option to buy ready-to-run systems. Tenstorrent, however, sees a developer community and software ecosystem as essential to the long-term success of a processor vendor. The company presented its open-source stack and described how developers can contribute to it at any level, facilitated by its use of hundreds of C-programmed RISC-V CPUs.

AI Networking at Hot Chips 2024

Networking is critical to building a Blackwell cluster, and Nvidia showed InfiniBand, Ethernet, and NVLink switches based on its silicon. The NVLink switch picture reveals a couple of interesting challenges to scaling out AI systems. Employing 200 Gbps serdes, signals in and out of the NVLink chips must use flyover cables, shown in blue and pink in Figure 1, because PCBs can’t handle the data rate. Moreover, the picture suggests the blue lines connect to front-panel ports, indicating customers’ data centers don’t have enough power to support 72-GPU racks and must divide this computing capacity among two racks.

Figure 1. Nvidia NVSwitch. (Source: Nvidia)

Short-hop links eventually will require optical networking. Broadcom updated the audience on its efforts developing copackaged optics (CPO). Having created two CPO generations for its Tomahawk switch IC, Broadcom completed a third CPO-development vehicle for an NPU. The company expects CPO to enable all-to-all connectivity among 512 NPUs. Intel also discussed its CPO progress. Disclosed two years ago, Intel’s key technology is an eight-laser IC its CPO design integrates, replacing the conventional external light source Broadcom requires.

Software and networking intersect at protocol processing. Hyperscalers employ proprietary protocols, adapting the standard ones to their data centers’ rigorous demands. For example, in presenting its homegrown Maia NPU, Microsoft alluded to the custom protocol it employs on the Ethernet backbone connecting a Maia cluster. Seeing standards’ inadequacies but also valuing their economies, Tesla presented its TTPoE protocol, advocating for the industry to adopt it as a standard. It has joined the Ultra Ethernet Consortium (UEC) and submitted TTPoE. Unlike other Ethernet trade groups focused on developing a new Ethernet data rate, the UEC has a broader mission to improve the whole networking stack.

Alternative Memory Hierarchies at Hot Chips 2024

Despite Nvidia’s success, a GPU-based architecture is suboptimal for AI acceleration. Organizations that started with a clean sheet have gone in different directions particularly with their memory hierarchies. Hot Chips 2024 highlighted several different approaches. The Meta MTIA accelerator has SRAM banks along its sides and 16 LPDDR5 channels, eschewing HBM. By contrast, Microsoft distributes memory among Maia’s computing tiles and employs HBM for additional capacity. In its Blackhole NPU, Tenstorrent similarly distributes SRAM among computing tiles and avoids expensive HBM, using GDDR6 memory instead. SambaNova’s SN40L takes a “yes-and” approach, integrating prodigious SRAM, including HBM in the package, and additionally supporting standard external DRAM. For on-chip memory capacity, nothing can touch the Cerebras WS-3 because no other design comes close to its wafer-scale integration.

CPUs Still Matter

AMD, Intel, and Qualcomm discussed their newest processors, mostly repeating information previously disclosed. Ampere discussed the Arm-compatible microarchitecture employed in the 192-core AmpereOne chip, revealing it to be in a similar class as the Arm Neoverse-N2 and adapted to many-core integration.

The RISC-V architecture is the standard for NPUs, being employed by Meta, Tenstorrent, and others. The architecture was also the subject of a presentation by the Chinese Academy of Sciences. The organization has two open-source projects under its XiangShan umbrella, which covers microarchitecture, chip generation, and development infrastructure. Billed as comparable to an Arm Cortex-A76, the Nanhu microarchitecture shown in Figure 2 is a RISC-V design focused more on power- and area-efficiency than maximizing performance. The Kunminghu microarchitecture is a high-performance RISC-V design the academy compares with the Neoverse-N2. Open source, and thus freely available, these CPUs present a business-model challenge to the many companies developing and hoping to sell RISC-V cores.

Figure 2. Nanhu microarchitecture (source: https://github.com/OpenXiangShan)

Bottom Line

Artificial-intelligence mania is propelling chip and networking developments. The inescapable conclusion, however, is that too many companies are chasing the opportunity. Beyond the companies highlighted above, others presented their technologies—a key takeaway about each is available at xpu.pub. The biggest customers are the hyperscalers, and they’re gaining leverage over merchant-market suppliers by developing their own NPUs, such as the Meta MTIA and Microsoft Maia presented at Hot Chips 2024.

Nvidia’s challengers, therefore, are targeting smaller customers by employing various strategies, such as standing up their own data centers (Cerebras), offering API access and selling turnkey systems (SambaNova), or fostering a software ecosystem (Tenstorrent). The semiconductor business, however, is one of scale economies, and aggregating small customers’ demand is rarely as effective as landing a few big buyers.

Although less prominent, RISC-V is another frothy technology. An open-source instruction-set architecture, it also has open-source implementations. Businesses have been built around Linux, but they involve testing, improving, packaging, and contributing to the open-source OS, not replacing it. Their business model could be a template for CPU companies, which have focused on developing better RISC-V implementations—which could be fruitless given the availability of high-end cores like Kunminghu.

At some point, both the AI and RISC-V bubbles will burst. If it happens in the next 12 months, we’ll learn that Hot Chips 2024 was the zenith of hype.

Endless Loop of Sanctions rotates while China buys more

Embargoes and other fun stuff in the Semiconductor Tools Market

While this post dives into the semiconductor tool market’s Q2 data, it is also about the senseless embargo game currently in place. The post illustration shows what my notebooks look like as embargoes enforce what they are supposed to suppress and are replaced by even more restrictive embargoes that… You get the point.

I don’t take sides in the Chip Wars or have an opinion about whether embargoes are needed or justified. I investigate what is going on.

I know that “Business will find a way” (inspired by Michael Crichton’s Jurassic Parc Quote: Life will find a way). The AI part of the embargos has been covered in the post: Pulled out of the black well.

The Semiconductor Tools Market

From a relatively quiet life away from the international spotlight, the Semiconductor Tools companies were propelled onto the geopolitical stage as semiconductors became a matter of national security—first for the US, later for its economic allies, and finally everywhere.

After AI showed its face and made Nvidia a superstar, Non-semiconductor insiders realised that none would be possible without factories in Taiwan and tools from the borderlands of the Nederlands and Belgium.

Despite decades of plentiful investments, the Chinese could not crack the macadamia nut of Semiconductors: Advanced lithography tools.

One company had orchestrated an incredibly advanced R&D effort throughout its supply chain and churned out machines capable of printing the small geometries needed for the most advanced technologies.

The US realised that despite retaining design dominance in Semiconductors, the manufacturing had slipped to Korea and Taiwan and with it, the supply chains.

The Chips Act could stimulate the growth of advanced US manufacturing capacity, but it could do little to remove the reliance on advanced European manufacturing capacity.

Even with the Chips Act, success was not guaranteed as the Chinese had invested in Semiconductor capacity for decades. The US government had to stop the flow of advanced lithography tools to China. Time for embargos.

ASML Embargoes

The US embargoes on AMSL sales to China are delicate as the US has to rely on relationships with the Dutch government. As the ASML sales to China are significant, significant commercial interests are at play.

The embargos started in 2019 with a ban on Extreme UV tools to China capable of better than 7nm processes. These have later been tightened in both 2023 and in the beginning of 2024.

With a mixture of bans and licenses, the embargoes slide from licenses to bans and include more products. As there has been no decline in sales to China, we are likely to see more restrictions over the next period.

The latest development has been debacles between the US and the Nederlands if the embargoes are really driven by national security concerns or more by commercial interest. As a result, the Netherlands have fully aligned to the US restrictions and have taken over the duty of issuing licenses. This is applauded by ASML, which expects a more lenient treatment from the local authorities than the US government.

Before we dive deeper into the outcome of the embargoes, it is worth taking stock of the Semiconductor tools market and its latest results.

The Semiconductor Tools market

Before any chip is made, Semiconductor Tools need to be bought. Throughout the weeks-long journey from blank wafer to finished chip, a multitude of tools is required.

Incredibly simplified, the tools can be categorised as:

  1. Lithography – the application of the chip design onto the wafer
  2. Depositions – adding material layers
  3. Modification – changing material layers
  4. Removal – removal of material layers
  5. Other: Metrology, Cleans, Handlers and a multitude of specialised tools.

The tools are placed in the investment zone of our Semiconductor market model and are impacted by the Capital Expenditures of the 3 different categories of Chip manufacturers: IDM’s, Foundries and the FAB/Foundry semiconductor companies.

This is not a business for the faint of heart. A new leading-edge semiconductor fab now costs more than $50B$ to build, and 75% of that cost is tools. The most expensive tools are larger than a double-decker bus and cost more than 350B$

As the geometries become smaller, the chips become cheaper to produce, faster, and consume less power. However, the other side of the coin is that the design costs are skyrocketing, and the tool and factory costs are also increasing.

Comparing the revenue of semiconductor companies with that of tool companies generates the first insights into this development.

The starting point is the bottom of the 2019 semiconductor cycle, and as can be seen, the revenue of the tool companies is outgrowing the semiconductor revenue. The Foundry revenue growth mirrors this. In other words, the collective investment in tools and the manufacturing costs of fabless companies are increasing significantly.

It is not only from a revenue perspective that the tools business is interesting.

From an operating profit perspective, the tools business is more attractive than the foundry and Semiconductor businesses. Notably, most of the semiconductor companies’ Q2-24 profitability stems from Nvidia; without Nvidia, the growth of Semiconductor companies would be a measly 24%.

This is worth noting as an investor as this trend will not change any day soon.

The state of the Semiconductor Tool Companies

The following charts are based on the revenue of semiconductor tool companies, including service and other revenue. The pure tool analysis will follow.

After a growth streak following the latest upcycle, the combined revenue peaks around the introduction of the US Chips Act. This replaces growth with a relatively steady state, with revenues flatlining at around 22B$ and stable Gross and operating profits—nothing to see here.

The declining investments of Semiconductor companies were a direct result of the Chips Act, as projects were redirected to US soil.

This surprised the semiconductor tools companies, or it was too late for them to respond. The result has been an increasing level of inventory that is now double what it was in 2020.

Tool companies used to be concentrated in three countries: the US, Japan, and the Netherlands. At the beginning of the 2020s, only 3% of the revenue was outside these three countries, most of which was in China.

Despite a decade of massive semiconductor investments, these tools proved to be the most difficult to conquer. Success in semiconductor tools requires more than money.

Even after another half-decade, the same countries dominate, although China has worked hard to gain market share. From 3% at the beginning of the decade, China has now managed to get to 8.5% in market share, which is not cause for any celebration in Beijing.

The rapid CAGR growth stopped what was expected during the Chinese New Year of the Dragon but did not bounce back to the levels expected. The inventory position of the Chinese Tools companies indeed suggests that the Chinese tool customers are constipated and not ready to consume at the same levels,

The Chinese tool manufacturers almost exclusively sell to China, but these are not the only tools the Chinese tool customers buy.

The Semiconductor Tool market

After reviewing the Tool companies’ revenue, it is worth investigating the tool revenue of the top companies for more insights. The tool revenue excludes the service and other revenue of Semiconductor tool companies and is perfectly aligned with the CapEx of Semiconductor manufacturing companies.

The dominance of certain countries is due to the domination of a few companies in the Semiconductor tool market.

The top companies account for almost all of the Tool Revenue outside China, and each of the large ones has its own area of specialisation making most of them submarket leaders in subfields, most prominently ASML in lithography and AMAT in materials engineering.

Since introducing the Chips Act and sanctions on AI and advanced lithography tools, sales of Western semiconductor tools to China have exploded.

The revenue of Western tool sold to China grew in Q2 but the Chinese share of revenue declined slightly from 45% in Q1 to 44.4% in Q2. I am sure this is no cause for a victory lap in Washington.

The dominance is even more apparent when compared to revenue from other countries.

The most apparent effect of the Chips act was that TSMC stopped investing in tools as projects were redirected to the US.

Excluding Chinese revenue from the revenue of Western Tool Companies shows the dilemma. China is not only a pain but also a saviour.

This is a crucial problem for the US policy of embargoes. It impacts other countries’ economies, especially when a large company like ASML resides in a small country.

In the last few weeks, there has been a lot of back and forth between Holland and the US government. AMSL has accused the US authorities (in what I cannot believe is not aligned with the Dutch government) of leaning more towards commercial interests than national security interests. At the same time, the Dutch government aligned their restrictions to the US restrictions, so it is now the Dutch authorities that will approve export licenses rather than the US government, something that I am sure ASML is very happy about (I don’t know why…)

China has also threatened Japan with retaliation should the country further sanction tool sales to China.

Conclusion

The US embargoes are focused on preventing the Chinese authorities from accessing leading-edge AI technology. Half of the embargoes are aimed at the GPUs, and the other half are focused on the tools. Memory might be next.

During the last few days, there have been many examples of how easy it is for Chinese companies to buy Nvidia’s H100 or rent it online cheaper than in the West. At the same time, Nvidia’s sales to China are once again increasing despite the embargoes.

The Semiconductor Tools sanctions are in place to prevent the Chinese from gaining access to leading-edge manufacturing technology, which would enable China to make its own GPUs.

The US keeps tightening the sanctions on Semiconductor tools but as with the GPUs, every new sanction seems to enforce what was put in place to inhibit.

I am sure the US authorities are thinking about even more draconian embargos against China, like the Foreign Direct Product Rule that would require the US to dictate all tool sales to China (as they all contain US technology) or try to prevent AMSL and other companies from servicing the existing installed equipment in China.

This would significantly negatively impact ASML and the Dutch economy and would be difficult for the US to get an agreement on.

In this post, I have tried to lay out the result (or lack thereof) of the sanctions in the semiconductor tools market. Tool sales to China remain strong despite increasing embargoes. In my experience, embargoes don’t stop the flow of products; they might change the flow or the cost, but eventually, business will find a way. I accept embargoes might play a political role, but that is not my area of expertise.

I leave you with a chart of Western tool companies’ cumulative sales to China and the US. Since 2019, China has bought nearly $100B worth of Semiconductor tools. More than 2.5 times what the US has bought in the same period. My apologies if that disturbs anybody’s sleep.

KLA Metrology and Inspection

Strong pull from N3 and N2

adv packaging growth from 300m to 500m$ in 2024

Packaging will outgrow WFE

No memory growth yet – will be 2025 and lead by DRAM

KLA share of WFE will grow

DRAM will have higher process control intensity

But it’s not contributing to that they are going to build capacity based on demand. The demand is just going to be based on their market, the overall market, and then they’ll buy equipment accordingly. But we are not counting on our customers to get ChipPAC money to make our plans.

ASML

We also see continued improvement in lithography tool utilization level at both Logic and Memory customers, all in line with the industry’s continued recovery from the downturn.

Lower logic revenue as customers trying to digest last years addition

an increase of EUV use on every node. I think this is a trend that continue at least in the foreseeable future

I think you have seen also in DRAM that this point of time, all customers are using EUV in production

On High NA, we also see opportunity for DRAM at the horizon of ’25, ’26.

LAM

Lam customer investment profile generally unchanged from prior view

+ Slightly stronger domestic China spending

+ Additional demand related to HBM capacity ramp

+ Foundry/logic, DRAM, and NAND investments all expected to be higher on a year-on-year basis

+ Global spending on mature nodes expected to be roughly flat year-on-year

Semiconductor Industry Update Webinar – Registration Now Open

Taken at face value, the headline annualized growth numbers look good, with Memory leading the charge and AI GPUs flying off the shelf but delving into the detail and a much bleaker picture emerges. Inventory levels remain stubbornly high, dampening unit demand, and the global economy is weak, neither of which bodes well for the industry moving forward.

Calibre DesignEnhancer Improves Power Management Faster and Earlier

Calibre DesignEnhancer Improves Power Management Faster and Earlier

Calibre DesignEnhancer Improves Power Management Faster and Earlier

Anyone who has attempted to implement a custom design in an advanced process node knows that effective power management can be quite challenging. Effects such as voltage (IR) drop and electromigration (EM) can present significant headaches for both design teams and foundries. Optimizing layouts for these kinds of issues is tricky. Design and P&R tools are intended for optimal design creation and implementation. Layout optimization can be an afterthought. Design for manufacturing (DFM) layout tools are good at optimization, but they are used at signoff, and the goal is to use it earlier in the design flow. There is a technical paper from Siemens Digital Industries Software that details an effective solution to this dilemma. A link is coming, but let’s first examine some details to see how Calibre DesignEnhancer improves power management faster and earlier.

About the Publication and the Author

Jeff Wilson

The paper from Siemens is entitled Calibre DesignEnhancer Design-Stage Layout Modification Improves Power Management Faster and Earlier. The author is Jeff Wilson, a product management director for DFM applications in the Calibre organization at Siemens Digital Industries Software.

Jeff is responsible for the development of products that analyze and modify IC layouts to improve the robustness and quality of the design. Before joining Siemens, he worked at Motorola and SCS. He holds a B.Sc. in design engineering from Brigham Young University and an MBA from the University of Oregon.

Jeff has quite a passion for layout optimization, and it comes through clearly in this well organized and insightful technical paper. You can see a short video of Jeff providing an overview of Calibre DesignEnhancer. A link to that is coming as well.

The Problem

At advanced process nodes, the challenge of managing capacitance and resistance impacts rises sharply. For example, going from 16nm to 5nm we see a max resistance increase around 6X. Over-designing the power grid results in wasted area. Under- designing can result in the IC never achieving IR and EM requirements. What is needed is a solution where the power grid is designed to be efficient for most of the design and optimized for areas of the layout that must support greater power usage.

Custom/analog designers and design implementation engineers have all the physical details needed for accurate and efficient layout optimization. However, applying layout modifications during design and implementation has typically been difficult and/or time-consuming. As discussed, most design and P&R tools provide native options that allow engineers to apply some layout optimization changes to layouts, but custom design and P&R tools are designed and intended for design creation and implementation. The result is sub-optimal layout optimization.

Some of the specific challenges to be met here include IR drop and electromigration.  For the first item, the overall size of the chip may be similar at advanced nodes, but the transistors and interconnect are packed into a smaller area. Typically, that results in the interconnect becoming narrower, which increases the unintended (parasitic) resistance, causing the voltage of the current traveling through that interconnect path to decrease over the length of the path (IR drop).

For the second item, metal atoms can be “pushed” out of place by the flow of current through the interconnect. Over time, the movement of these metal atoms creates both empty spaces (voids) and piles of atoms (hillocks) in the interconnect. If the voids become wide and/or deep enough, they create an open circuit in the interconnect, while hillocks can grow high enough to connect to other interconnects, creating a short. This is a ticking time bomb in advanced circuits that needs to be handled carefully. The figure below illustrates what can happen.

Electromigration Issues

The Solution – Design Stage Layout Modification

To ensure a design remains compliant with design rule checking (DRC) constraints, all layout modifications must be applied with a deep understanding of complex design rules and connectivity requirements. The Calibre DesignEnhancer tool provides an analysis-based solution integrated with both design and P&R flows to help custom designers and P&R engineers efficiently and accurately reduce IR drop and EM issues without negatively impacting performance and area. The tool is used early in the design process, creating a Shift-Left solution that optimizes results and avoids long design/analysis loops.

This approach prepares layouts for physical verification more quickly with minimal issues encountered. Multiple automated layout enhancement use models accessing proven, foundry- preferred rule decks provide optimized layout modifications while ensuring all layout changes are Calibre-clean. The technical paper goes into significant detail about the challenges in advanced designs and how Calibre DesignEnhancer addresses those challenges. If advanced node design is in your future, you need to download this technical paper to improve your chances of success

A download link is coming. First, I will summarize the solutions presented in the paper.

The Calibre DesignEnhancer tool currently provides three use models:

Via insertion, that automatically adds Calibre-clean vias to reduce IR drop and moderate the impact of via resistance on manufacturability and reliability.

Parallel run lengths insertion with the power grid enhancement (Pge) use model that automatically reduces resistance by finding open tracks and inserting Calibre-clean metal and vias to create these parallel runs.

Filler/DCAP cell insertion. In this case, open areas that are left between cells after P&R must be filled before physical verification can be run. These gaps are filled with filler cells (non-functional cells used to continue the rails as required for layer continuity and alignment, such as power/ground and Pwell/Nwell) and DCAP cells (temporary capacitors added between power and round rails to counter functional failures due to IR drop).

By replacing time-consuming and limited P&R filler cell insertion processes with the push-button Calibre DesignEnhancer Pvr use model and its knowledge of Vt rules, design teams can ensure not only Calibre-clean filler and DCAP cells, but also electrically-correct layouts, while also reducing filler cell and DCAP cell insertion runtimes.

These three use models are the inspiration for the graphic at the top of this post. The paper also details the design flow, compatibility with commercial tools and presents several detailed results.

To Learn More

Now it’s time to get your copy of this technical paper and prepare for your next advanced node design. You can download the paper here. And if you have a couple of minutes you can watch a great overview video presented by Jeff Wilson at the top of this page. And that’s how Calibre DesignEnhancer improves power management faster and earlier.
