Create an install directory (avoid system-owned folders like /usr/local to prevent permission issues):

QuestaSim Starter Version 202x.x ... To compile and simulate a tiny design:

mkdir -p ~/intelFPGA/questa_sim chmod +x questasim-linux_x86_64-202x.x.run ./questasim-linux_x86_64-202x.x.run --mode text --prefix ~/intelFPGA/questa_sim For GUI installer (if you have X11 forwarding):

Happy simulating on Linux!

export QUESTA_HOME=~/intelFPGA/questa_sim export PATH=$QUESTA_HOME/bin:$PATH export LM_LICENSE_FILE=1717@localhost # only for floating license export MGLS_LICENSE_FILE=$LM_LICENSE_FILE Then reload:

./questasim-linux_x86_64-202x.x.run Follow the prompts. When asked for license type, choose if using Starter Edition. Step 5: Set Up Environment Variables Add to your ~/.bashrc or ~/.profile :
