While writing “Mobile Unleashed: The Origin and Evolution of ARM Processors In Our Devices” it was very clear to me that ARM was an IP phenomenon that I did not believe would ever be repeated. Clearly I was wrong as we now have RISC-V with an incredible adoption rate, a full fledged ecosystem, and top tier implementers… Read More





Desperation Drives Inspiration
This is the tenth in the series of “20 Questions with Wally Rhines”
1978 was a bad year for TI. In April, Intel announced the 8086 followed by disclosures of 16-bit microprocessors from Motorola, the 68000, and Zilog, the Z8000. TI had tried to leapfrog the microprocessor business by introducing the TMS 9900 16-bit … Read More
Living on the (IoT) Edge
The phrase “where the rubber meets the road” is especially apt when it comes to discussions about the Internet of Things. The obvious interpretation is that dissimilar things are being put together in a mutually dependent fashion. When I hear the phrase I always think of the things that can go wrong, such a tire sliding instead of … Read More
Machine Learning with Prior Knowledge
I commented recently on limitations in deep learning (DL), one of which is the inability to incorporate prior knowledge, like basic laws of mathematics or physics. Typically, understanding in DL must be inferred from the training set, which in a general sense cannot practically cover prior knowledge. Indeed one of the selling… Read More
Enhancing Early Static FSM
Finite state machines (FSMs) are widely adopted as part of reactive systems to capture their dynamic behaviors using a limited number of modes or states that usually change according to the applied circumstances. Some terminologies are frequently used to describe the FSM characteristics: state, transition, condition and … Read More
Tesla Leap of Faith (or the Adoration of Elon Musk)
The Reverend Elon Musk, CEO of Tesla Motors, held forth to his flock on yesterday’s earnings call. Musk described at length his efforts to lead the company out of production hell. The lengthy session highlighted the challenges facing the company, which posted its greatest quarterly loss ever, and was emblematic of the typical … Read More
Timing Closure Techniques for SOCs with Embedded FPGA Fabric
Once the benefits of using an embedded FPGA fabric are understood, the next question is about how timing closure is handled between the ASIC and the eFPGA blocks. First let’s look briefly at the advantages. By moving the eFPGA on to the SOC die, tons of I/O logic and the need for any package and board interconnect will vanish. Package… Read More
Timing Channel Attacks are Your Problem Too
You’ve heard about Meltdown and Spectre and you know they’re really bad security bugs (in different ways). If you’ve dug deeper, you know that these problems are related to the speculative execution common in modern processors, and if you dug deeper still you may have learned that underlying both problems are exploits called timing… Read More
Cadence Update on AMS Design and Verification at #55DAC
As a blogger in the EDA industry I get more invitations to meet with folks at DAC than I have time slots, so I have to be a bit selective in who I meet. When the folks at Cadence asked me to sit down and chat with Mladen Nizic I was intrigued because Mladen is so well-known in the AMS language area and he’s one of the authors of, The Mixed-Signal… Read More
Synopsys Offers First Single-Vendor Comprehensive Photonic IC Design Flow
Synopsys has a long history of being a thought leader and it’s not surprising to see the company jumping into the forefront of new technologies. For decades, I’ve been steeped in electronic IC design and it caught me by surprise to find that Synopsys had been quietly working on filling out their portfolio in the optical design solutions… Read More
