Now I'm can run it with ./vsim command from folder /quartus/modelsim_ase/linuxaloem
when I'm put vsim, get
No command 'vsim' found, did you mean: ...
but when I'm try run leon3 simulation from grlib via make vsim-launch I'm get
/bin/sh: 1: vsim: not found
You can go to the bin directory of the Modelsim installation and do './vsim' . If that works add the bin path to your ~/.bashrc
