verilator check doesn't print anything #5

Hello! I have an issue, while running 'make' for verifing the IOMMU IP. Verilator 4.110 runs, but doesn't print anything. Is that okay? image

The Makefile only makes lint checks. As far as I remember, it won't output something if everything is OK. If you want to play with the IOMMU, it may be interesting to go through their demo where IOMMU is integrated in a CVA6: https://github.com/zero-day-labs/riscv-iommu-demo (btw, I'm making experiments with that repo :wink:)

okay thanks! Could I use the CVA6+iommu with verilator?

pcotret commented 8 months ago

There's an feat/iommu branch in their CVA6 fork (https://github.com/zero-day-labs/cva6/tree/feat/iommu). Not sure if this branch is fully functional.

Okay thank you very much
