It's cool to learn about Verilator: I've been proposing our HW teams give us the simulations based on their HW design for us to target with SW, but I am so out of the loop on HW development, that I can't push them in this direction (because they'll just give me: "that's interesting, but it's hard", which frustrates me to no end).
Can you perhaps do a write-up of what you've done and how "slow" it was, and if you've got ideas to make it faster?
The hardest part is toolchains, for two reasons. First, Verilator doesn't have complete SV language support, although it's gotten better. Second, hardware has a tendency to accumulate some of the most contorted build systems I've ever seen and most hardware engineers don't actually know how to extricate it.
Once it's actually successfully run through Verilator, it's a C++ interface. Very easy to integrate if your sim already has a notion of "clock tick."
