OneSpin Solutions
The next presentation was from OneSpin Solutions. This company provides formal-verification tools for RISC-V Cores. What was memorable from this presentation were the bugs that their tools found in some open-source RISC-V cores. It was explained that RISC-V cores are challenging to verify because there are many optional instructions; complex micro-architectures are permitted, not to mention custom instructions.
The OneSpin Formal Verification tool provides complete coverage and guarantees full compliance to the RISC-V ISA and privileged ISA. OneSpin ran the open-source cores RI5CY and Rocket through its tool. Both designs had more than five issues, which were reported to the developers.
