This is really great. OpenTitan has some useful IP components that can definitely be reused, and it's really cool that this is open. Nice one Google. I have to minority nitpick though:
> both individual IP blocks and the top-level Earl Grey design have functional and code coverage above 90%—to the highest industry standards—with 40k+ tests running nightly
This is definitely not "to the highest industry standards". I've worked on projects where we got to 100% on both for most of the design. It's definitely a decent commercial standard though - way above most open source verification quality.
