yes.  https://git.libre-soc.org/?p=dev-env-setup.git;a=blob;f=ghdl-install;hb=HEAD
i'm not sure why ghdl-yosys-plugin isn't in that.  if you'd like to
add it feel free

ah no.  well... yes, but you need specific options
$ python3 simple/issuer_verilog.py --microwatt-compat --enable-mmu
external_core_top.v >& /tmp/f1

then copy that into the microwatt directory, you will need the verilator_trace
branch:
