Information Flow Tracking at RTL. Innovation in Verification
by Bernard Murphy on 12-27-2023 at 6:00 am

Innovation New

Explicit and implicit sneak paths to leak or compromise information continue to represent a threat to security. This paper looks a refinement of existing gate level information flow tracking (IFT) techniques extended to RTL, encouraging early-stage security optimization. Paul Cunningham (Senior VP/GM, Verification at … Read More

ML-Guided Model Abstraction. Innovation in Verification
by Bernard Murphy on 11-29-2023 at 6:00 am

Innovation New

Formal methods offer completeness in proving functionality but are difficult to scale to system level without abstraction and cannot easily incorporate system aspects outside the logic world such as in cyber-physical systems (CPS). Paul Cunningham (Senior VP/GM, Verification at Cadence), Raúl Camposano (Silicon Catalyst,… Read More

Developing Effective Mixed Signal Models. Innovation in Verification
by Bernard Murphy on 10-30-2023 at 6:00 am

Innovation New

Mixed-signal modeling is becoming more important as interaction between digital and analog circuitry become more closely intertwined. This level of modeling depends critically on sufficiently accurate yet fast behavioral models for analog components. Paul Cunningham (Senior VP/GM, Verification at Cadence), Raúl Camposano… Read More

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

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

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

Innovation New

Constrained random methods in simulation are universally popular, still can the method be improved? 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 research ideas. As always, feedback welcome.… Read More
