Assertion Synthesis Through LLM. Innovation in Verification

Assertion Synthesis Through LLM. Innovation in Verification
by Bernard Murphy on 09-28-2023 at 6:00 am

Innovation New

Assertion based verification is a very productive way to catch bugs, however assertions are hard enough to write that assertion-based coverage is not as extensive as it could be. Is there a way to simplify developing assertions to aid in increasing that coverage? Paul Cunningham (Senior VP/GM, Verification at Cadence), Raúl … Read More

Cadence Tensilica Spins Next Upgrade to LX Architecture

Xtensa LX8 processor

When considering SoC architectures it is easy to become trapped in simple narratives. These assume the center of compute revolves around a central core or core cluster, typically Arm, more recently perhaps a RISC-V option. Throw in an accelerator or two and the rest is detail. But for today’s competitive products that view is a … Read More

Support for AI at the edge has prompted a good deal of innovation in accelerators, initially in CNNs, evolving to DNNs and RNNs (convolutional neural nets, deep neural nets, and recurrent neural nets). Most recently, the transformer technology behind the craze in large language models is proving to have important relevance at… Read More


Mixed Signal Verification is Growing in Importance

Mixed Signal Verification is Growing in Importance
by Bernard Murphy on 09-07-2023 at 6:00 am

Mixed signal min

I have historically avoided mixed signal topics, assuming they decouple from digital and can be left to the experts. That simple view no longer holds water. Analog and digital are becoming more closely linked through control loops and datapaths, requiring a careful balancing act in verification between performance, accuracy… Read More

Anomaly Detection Through ML. Innovation in Verification
by Bernard Murphy on 08-31-2023 at 6:00 am

Assertion based verification only catches problems for which you have written assertions. Is there a complementary approach to find problems you haven’t considered – the unknown unknowns? Paul Cunningham (Senior VP/GM, Verification at Cadence), Raúl Camposano (Silicon Catalyst, entrepreneur, former Synopsys CTO and now… Read More

Joules RTL Design Studio Benefits

Register Transfer Level (RTL) is a crucial and valuable concept in digital hardware design. Over the years, it has played a fundamental role in enabling design of complex digital chips. By abstracting away implementation details and providing a clear description of digital behavior, RTL has contributed significantly to the… Read More

Cadence, AI, #60DAC min

Paul Cunningham from Cadence presented at the #60DAC Pavilion and gave one of the most optimistic visions of AI applied to EDA that I’ve witnessed, so hopefully I can convey some of his enthusiasm and outright excitement in my blog report. Mr. Cunningham reviewed the various ages of EDA design with each era providing about… Read More

Innovation New

A little thinking outside the box this time. Microsoft is adding automation to their (and LinkedIn) code reviews; maybe we should consider this option also? Paul Cunningham (Senior VP/GM, Verification at Cadence), Raúl Camposano (Silicon Catalyst, entrepreneur, former Synopsys CTO and now Silvaco CTO) and I continue our series… Read More

MIDAS System min

While fully autonomous driving may now be a distant dream, ADAS continues to be a very active industry driver as much for its safety advantages as for other features. Today in the hierarchy of SAE levels, SAE 2+ may represent the most active area of development rather than levels 3 through 5. This range of options still requires a human… Read More


Convergence Between EDA and MCAD and Industrial Software

Convergence Between EDA and MCAD and Industrial Software

convergence eda mcad etc min

Cadence hosted a panel at DAC on how EDA, MCAD and industrial software have come together, a topic I always find interesting. Many years ago, I worked on a NAVAIR contract bid team, an eye-opener for a young engineer who thought that innovation started and ended with electronic design. I remember CATIA (3D modeling) being a component… Read More
