Hi Simon,
May I know which Quartus version that you have used?
If you are using the legacy version, by right the command that you mention should be work.
If it is not working, then I think that it is a bug.
But I'm sorry for this because the engineer wont be prioritized to fix the legacy software as it's going to EOL.
Have you try to generate by using GUI?
If yes, do the files still be generated even if they are not selected?
To workaround of this problems, you may try to use different version of Quartus.
Regarding to your question, you may generate only the synthesis or only the simulation.
- Run make_qii_design.tcl for synthesis.
- Run make_sim_design.tcl for simulation.
Thanks.
