Question
I have a valid FST file generated by my own simulation toolchain. When I try to convert it to VCD using fst2vcd, it is blocked by the TALOS-2023-1791 security check. The file opens fine in GTKWave and all signals are visible, so I know the file is not malicious.

VRvvCoreMiniAxi.core.fst.gz

I also tried File → Export → Write VCD File from the GTKWave GUI but the exported VCD is missing signals.

Is there any workaround or flag (e.g. --force, --skip-security-check) to bypass the TALOS check so I can get a VCD out of this file?

Command

fst2vcd -f VRvvCoreMiniAxi.core.fst -o test_waves.vcd

Output

Triggered TALOS-2023-1791 security check, exiting.
