I imagine that the title of this post will remind many of 80s synth-pop, or perhaps the movie The Breakfast Club. But my topic is the venerable hardware verification language (HVL) known simply as e. It has quite an interesting history and it played a key role in the development of the modern testbench methodology that most chip verification… Read More

SoC verification has always been an interesting topic for me. Having worked at companies like Zycad that offered hardware accelerators for logic and fault simulation, the concept of reducing the time needed to verify a complex SoC has occupied a lot of my thoughts. The bar we always tried to clear was actually simple to articulate… Read More


Simulation and Formal – Finding the Right Balance

Simulation and Formal – Finding the Right Balance
by Bernard Murphy on 01-23-2018 at 7:00 am

Simulation dominates hardware functional verification today and likely will continue to dominate for the foreseeable future. Meanwhile formal verification, once thought to be a possible challenger for the title, has instead converged on a more effective role as a complement to simulation. Formal excels at finding problems… Read More


Anirudh on Verification

I was fortunate to have a 1-on-1 with Anirudh before he delivered the keynote at DVCon. In case you don’t know the name, Dr. Anirudh Devgan is Executive VP and GM of the Digital & Signoff Group and the System & Verification Group at Cadence. He’s on a meteoric rise in the company, not least for what he has done for Cadence’s position… Read More


Simulation done Faster

Simulation done Faster

When it comes to functional verification of large designs, huge progress is being made in emulation and FPGA-based prototyping (about which I’ll have more to say in follow-on blogs), but simulation still dominates verification activity, all the way from IP verification to gate-level signoff. For many, while it is much slower… Read More
