Smarter Verification: Shift Mindset to Shift Left [Video]

Thursday, March 5th, 2015

The Design and Verification Conference Silicon Valley was held this week.  During Aart de Geus’ keynote, he shared how SoC verification is “shifting left”, so that debug starts earlier and results are delivered more quickly.   He identified a number of key technologies that have made this possible:

  • Static verification that uses a mix of specialized code analysis and formal technology which are must faster and more focused than traditional simulation
  • New third generation of analysis engines
  • Advancements in debug

Real Intent has also been talking about this new suite of technologies that improve the whole process of SoC verification.  Pranav Ashar, CTO at Real Intent wrote about these in a blog posted on the EETimes web-site.  Titled “Shifting Mindsets: Static Verification Transforms SoC Design at RT Level“, it introduces the idea of objective-driven verification:

We are at the dawn of a new age of digital verification for SoCs. A fundamental change is underway. We are moving away from a tool and technology approach — “I have a hammer, where are some nails?” — and toward a verification-objective mindset for design sign-off, such as “Does my design achieve reset in two cycles?”

Objective-driven verification at the RT level now is being accomplished using static-verification technologies. Static verification comprises deep semantic analysis (DSA) and formal methods. DSA is about understanding the purpose and intent of logic, flip-flops, state machines, etc. in a design, in the context of the verification objective being addressed. When this understanding is at the core of an EDA tool set, a major part of the sign-off process happens before the use or need of formal analysis. (more…)
