For the devices we build today, design and implementation are unavoidably entangled. Design for low-power, test, reuse and optimized layout are no longer possible without taking implementation factors into account in design, and vice-versa. But design teams can’t afford to iterate indefinitely between these phases, so they… Read More

Open-Silicon Update: 125M ASICs shipped!
As you all know I am a big fan of the ASIC business model. It was critical in the transformation of the fabless semiconductor industry and still plays a critical part in our success. In fact, the ASIC business model is leading the way for systems companies to make their own chips. Remember, Apple started with the ASIC business model … Read More
How ARM designs and optimizes SoCs for low-power
ARM has become such a worldwide powerhouse in delivering processors to the semiconductor IP market because they have done so many things well: IP licensing model, variety, performance, and low-power. On my desk are two devices with ARM IP, a Samsung Galaxy Note 4 smart phone and a Google tablet. Most of my readers will likely have… Read More
How to nail your PPA tradeoffs
How do you ensure your design has been optimized for power, performance, and area? I posed this question to Mentor’s Group Director of Marketing, Sudhakar Jilla and product specialist Mark Le. They said that finding the PPA sweet spot is still often done by trial and error – basically serial experiments with various input parameters… Read More
Achieving Lower Power through RTL Design Restructuring (webinar)
From a consumer viewpoint I want the longest battery life from my electronic devices: iPad tablet, Galaxy Note 4 smart phone, Garmin Edge 820 bike computer, and Amazon Kindle book reader. In September I blogged about RTL Design Restructuring and how it could help achieve lower power, and this month I’m looking forward to … Read More
A Credible Player at the Power Table
For a while it seemed like Mentor lived on the margins of the (RTL) design-for-power game. They had interesting micro-architectural optimization capabilities through their Calypto heritage but no real industry chops in power estimation, a must-have when you are claiming to reduce power. Better known offerings in RTL power … Read More
High Level Synthesis Update
High-level synthesis (HLS) involves the generation of an RTL hardware model from a C/C++/SystemC description. The C code is typically referred to as abehavioraloralgorithmicmodel. The C language constructs and semantics available to architects enable efficient and concise coding – the code itself is smaller, easier to write/read,… Read More
A Versatile Design Platform with Multi-Language APIs
In one of my whitepapers “SoCs in New Context – Look beyond PPA”, I had mentioned about several considerations which have become very important in addition to power, performance, and area (PPA) of an SoC. This whitepaper was also posted in parts as blogs on Semiwiki (links are mentioned below). Two important… Read More
A Brief History of Defacto Technologies
In early 2000s, semiconductor design at RTL level was gaining momentum. The idea was to process more design steps such as insertion of test and other design structures upfront at the RTL level. The design optimization and verification were to be done at the RTL level to reduce long iterations through gate level design because changes… Read More
Multi-Level Debugging Made Easy for SoC Development
An SoC can have a collection of multiple blocks and IPs from different sources integrated together along with several other analog and digital components within a native environment. The IPs can be at different levels of abstractions; their RTL descriptions can be in different languages such as Verilog, VHDL, or SystemVerilog.… Read More
