Palladium Protium

In verification there is an ever-popular question, “When can we stop verifying?” The intent behind the question is “when will we have found all the important bugs?” but the reality is that you stop verifying when you run out of time. Any unresolved bugs appear in errata lists delivered with the product (some running to 100 or more … Read More

Aart keynote

Synopsys pulled out all the stops for this event. I attended the first full day, tightly scripted from Aart’s keynote kick off to 1×1 interviews with Synopsys executives to a fireside chat between Sassine Ghazi (President and COO) and Rob Aitken (ex-Fellow at Arm, now Distinguished Architect at Synopsys). That’s a lot of … Read More

Core counts min

In the march to more capable, faster, smaller, and lower power systems, Moore’s Law gave software a free ride for over 30 years or so purely on semiconductor process evolution. Compute hardware delivered improved performance/area/power metrics every year, allowing software to expand in complexity and deliver more capability… Read More


AI in Verification – A Cadence Perspective

AI in Verification – A Cadence Perspective
by Bernard Murphy on 04-04-2023 at 6:00 am

Opening slide min

AI is everywhere or so it seems, though often promoted with insufficient detail to understand methods. I now look for substance, not trade secrets but how exactly they using AI. Matt Graham (Product Engineering Group Director at Cadence) gave a good and substantive tutorial pitch at DVCon, with real examples of goal-centric optimization… Read More


Speculation for Simulation. Innovation in Verification

Speculation for Simulation. Innovation in Verification

Innovation New

This is an interesting idea, using hardware-supported speculative parallelism to accelerate simulation, with a twist requiring custom hardware. 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 on… Read More

Space Perspective

Dirk Didascalou, Siemens CTO, gave a keynote at DVCon, raising our perspective on why we do what we do. Yes, our work in semiconductor design enables the cloud and 5G and smart everything, but these technologies push progress for a select few. What about the big global concerns that affect us all: carbon, climate, COVID and conflict?… Read More

Synopsys has posted on the SolvNet site a fascinating talk given by Dr. Theo Drane of Intel Graphics. The topic is datapath equivalency checking. Might sound like just another Synopsys VC Formal DPV endorsement but you should watch it anyway. This is a mind-expanding discussion on the uses of and considerations in formal which … Read More

I have a new-found respect for Lu Dai. He is a senior director of engineering at Qualcomm, with valuable insight into the ground realities of verification in a big semiconductor company. He is on the board of directors at RISC-V International and is chairman of the board of directors at Accellera, both giving him a top-down view of… Read More


Scaling the RISC-V Verification Stack

Scaling the RISC-V Verification Stack
by Bernard Murphy on 03-15-2023 at 6:00 am

RISC V verification stack

The RISC-V open ISA premise was clearly a good bet. It’s taking off everywhere, however verification is still a challenge. As an alternative to Arm, the architecture and functionality from multiple IP providers looks very competitive, but how do RISC-V providers and users ensure the same level of confidence we have in Arm? Arm … Read More
