Description:
When building ibex_simple_system_cosim with Verilator, the build process hangs indefinitely at the compilation stage.
Steps to reproduce:
fusesoc --cores-root=. run --target=sim --setup --build lowrisc:ibex:ibex_simple_system_cosim --RV32E=0 --RV32M=ibex_pkg::RV32MFast
Observed behavior:
The build passes all pre-build checks:
Verilator 4.210 (required 4.210) ✓
Edalize 0.6.8 (required 0.2.0) ✓
Co-simulation setup check ✓
Then hangs at:
INFO: Building simulation model
