Cool, except this seems to break the ClusteredRocketConfig 😢

[hansungk]

chipsalliance/rocket-chip#3718 should fix this

[jerryz123]

Can you add a CI test that builds+runs one of these configs? The test can be something very simple... just a hello world-like thing basically.

Is using VCS an option? forgot our Vortex fails to build in Verilator

[jerryz123]

Oh, in that case don't bother with testing the sim. You can just add a test that the verilog gets generated.

[jerryz123]

I would ask you to add a docs page, but you can do that in a follow-on PR so we can get this monster in. Feel free to merge ... ignore the CI failures related to firesim
