You should use SSH if you have a GitHub account and have already uploaded an OpenSSH public key to GitHub, otherwise use HTTPS if you have no account or you want to use login credentials.

Protocol GitHub Repository URL
SSH ssh://


Execute git checkout -b stable <tag> after git clone, to checkout a specific version of GHDL.

Command line instructions to clone GHDL with HTTPS protocol:

cd GitRoot
git clone "" ghdl
cd ghdl
git remote rename origin github

Command line instructions to clone GHDL with SSH protocol:

cd GitRoot
git clone "ssh://" ghdl
cd ghdl
git remote rename origin github
