Validating NoC Security. Innovation in Verification
by Bernard Murphy on 12-21-2022 at 6:00 am

Innovation New

Network on Chip (NoC) connectivity is ubiquitous in SoCs, therefore should be an attractive attack vector. Is it possible to prove robustness against a broad and configurable range of threats? Paul Cunningham (Senior VP/GM, Verification at Cadence), Raúl Camposano (Silicon Catalyst, entrepreneur, former Synopsys CTO and… Read More

Post-Silicon Consistency Checking. Innovation in Verification
by Bernard Murphy on 10-26-2022 at 6:00 am

Innovation New

Many multi-thread consistency problems emerge only in post-silicon testing. Maybe we should take advantage of that fact. 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,… Read More

Formal at System Level. Innovation in Verification
by Bernard Murphy on 07-27-2022 at 6:00 am

Innovation New

Formal verification at the SoC level has long seemed an unapproachable requirement. Maybe we should change our approach. Could formal be practical on a suitable abstraction of the SoC? Paul Cunningham (GM, Verification at Cadence), Raúl Camposano (Silicon Catalyst, entrepreneur, former Synopsys CTO and now Silvaco CTO) and… Read More
