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
Looking for better ways to search a huge state space in model checking, Ant Colony Optimization (ACO) is one possible approach. 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
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
Can we order regression tests for continuous integration (CI) flows, minimizing time between code commits and feedback on failures? 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.… Read More
Modeling and verifying asynchronous systems is a constant challenge. Petri net models may provide an answer. Paul Cunningham (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.
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
Artificially stalling datapaths and virtual channels is a creative method to uncover corner case timing bugs. A paper from Nvidia describes a refinement to this technique. Paul Cunningham (GM, Verification at Cadence), Raúl Camposano (Silicon Catalyst, entrepreneur, former Synopsys CTO and now Silvaco CTO) and I continue… Read More
This is another look at refining the accuracy of fault localization. Once a bug has been detected, such techniques aim to pin down the most likely code locations for a root cause. Paul Cunningham (GM, Verification at Cadence), Raúl Camposano (Silicon Catalyst, entrepreneur, former Synopsys CTO and now Silvaco CTO) and I continue… Read More
We’re always looking for ways to leverage machine-learning (ML) in coverage refinement. Here is an intriguing approach proposed by Google Research. Paul Cunningham (GM, Verification at Cadence), Raúl Camposano (Silicon Catalyst, entrepreneur, former Synopsys CTO and now Silvaco CTO) and I continue our series on research… Read More
We normally test only for correctness of the functionality we expect. How can we find functionality (e.g. Trojans) that we don’t expect? Paul Cunningham (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
