ModelSim on Ubuntu

Question

I just installed the latest version of ModelSim on Ubuntu 16.04.1. But I can't launch the software by using this command ./vsim. It always said

bash: ./vsim: No such file or directory

Can anybody help? Thanks.

Answer 1

This is most probably because you have a 64-bit system, but vsim is a 32-bit binary. Try the following (from https://askubuntu.com/a/454452):

sudo dpkg --add-architecture i386
sudo apt-get update
sudo apt-get install libc6:i386 libncurses5:i386 libstdc++6:i386

This did the trick for me on Debian Stretch, might help you too.

Answer 2

It sounds to me like you haven't set up your PATH environment variable correctly. You need to add the directory that vsim is in to your PATH system variable:

export PATH=$PATH:~/intelFPGA_lite/17.0/modelsim_ase/linuxaloem/

The PATH variable is a list of directories where the operating system is expecting to find executable commands.

Then test to see if this works. Now, you need to make this change permanent. Edit the .bash_profile file in your home directory. You will probably see that there are already additions to the PATH variable. You need to add the change you just tested.
