I am trying to install Quartus Lite 20.1 on my ubuntu 20.04 but then I get this error which I have no idea on how to fix it.

Error: cannot find "/opt/intelFPGA_lite/20.1/modelsim_ase/bin/../linux_x86_64/vsim"

I have attached attached the vsim file below which is quite different from the previous versions of Modelsim. For example this `vco="linux_rh60" ` no longer exist in the current ModelSim version.

I think it is best that you try to re-install the latest Quartus version and the corresponding Modelsim version. Check that the hardware and software requirement are met before installing.

Hi @MTett1,

I was able to workaround this issue exporting the following environmental variable:

export MTI_VCO_MODE=32

 

The problem seems to be that Modelsim detects that Ubuntu is a x64 OS, but the installer Modelsim Intel Starter Edition only can run in 32 bits mode.

Exporting that variable to your environment will make Modelsim to be executed in 32 bits regarding the OS architecture.

Regards
