### Additional commands ### Additional commands
* -ghdl *param*: Supply these arguments directly to GHDL (can be used multiple times) * -ghdl *param*: Supply these arguments directly to GHDL (can be used multiple times)
* -no-precompile: Compile the files not until calling vsim. (Faster syntax check, but longer wait time for the simulation to start.)
### Notes ### Notes
* *cwd* is expected to be the compile directory * *cwd* is expected to be the compile directory
