Running Intel QuestaSim failing with error

[magurmach]

I am treating this issue as a tracker for all errors I face for running vsim from Intel Questa (specifically from Quartus Prime Lite).

I am attempting to do hello world RTL simulation.

Specifically: app=hello_world make sim

Initial error:

# ** Error (suppressible): (vlog-12110) All optimizations are disabled because the -novopt option is in effect. This will cause your simulation to run very slowly. If you are using this switch to preserve visibility for Debug or PLI features, please see the User's Manual section on Preserving Object Visibility with vopt. -novopt option is now deprecated and will be removed in future releases.

After adding suppression for this by adding -suppress vlog-12110 to questa_args, I am getting the following error:

# vsim "+UVM_NO_RELNOTES" "+PRELOAD=/home/sshakib/riscv/ara/apps/bin/hello_world" -sv_lib work-dpi/ara_dpi -work work -voptargs="+acc" -suppress vsim-3009 -suppress vopt-7033 -suppress vlog-12110 work.ara_tb -do "../scripts/run.tcl"

Any idea what it means to recompile work.ara_tb_sv_unit?

Hi @magurmach,

I have never seen this problem. Have you tried to delete the build directory and re-compile with Questa? work.ara_tb_sv_unit is one of the library modules, the top-level one. Let me know if a fresh build folder solves the issue.
