Generation of verilog file for rocket chip about rocket-chip HOT 6 OPEN

You need to have firtool installed since that's what's doing the verilog generation. The project has moved to using nix for it's dependencies/environment management so you should try getting that set up.

I have set up nix in my system but how can I install firtool

from rocket-chip.

run nix develop, it will probably download and build tools which is necessary and includes firtool, if you want to download firtool binaries explicitly, download it from circt releases.

from rocket-chip.

I have similar troubles - got the latest firtool binaries from circt, and getting an error because option -dedup does not exist there, just -no-dedup. Removing -dedup from build.sc allows
make verilog
to not error out, but the next one form the README
make verilog CONFIG=DefaultSmallConfig
still errors out with
[build.sc] [47/53] zincReportCachedProblems
Cannot resolve emulator[freechips.rocketchip.system.TestHarness,DefaultSmallConfig].mfccompiler.compile. Try mill resolve emulator._ or mill resolve __.compile to see what's available.
Would be great if the README was more up to date (firtool is not mentioned at all).
