Episode 12: Finding corner-case bugs in processors using architectural formal verification
What happens when you apply formal verification to find architectural flaws in processors? In this podcast, Dr. Ashish Darbari talks about an interesting way of using Axiomise ISA formal proof kit to find bugs in RISC-V cores. He describes how by using the combination of automated formal properties from the Axiomise proof kit together with constraints we can not only find bugs but also root-cause the precise nature of simulation resistant bugs. You might like this podcast if you ever wondered how constraints together with automated formal can be used to address the complex challenges of finding corner-case bugs in your CPU designs.
