A patch to integrate Quartus Prime installed on Windows into WSL LiteX workflow.

Tested on WSL2.

Installation

If you are in the same directory as the patch file:

cd <path-to-your-litex-install>
patch -p1 < "$OLDPWD"/wsl-litex-quartus.diff

If LiteX was installed with Python venv, <path-to-your-litex-install> is <directory-with-litex_setup.py>/litex. Before installling, you might want to change the fallback for $LITEX_WIN32_QUARTUS_PATH in the patch file so you don’t have to set it on each new session (or just export the variable in venv activation script).

Environment Variables

• $WSL_DISTRO_NAME - is used to set the path to files for Quartus, ensure it is correct (should be set automatically)

• $LITEX_WIN32_QUARTUS_PATH - is the path to Quartus bin64 from within WSL, eg., /mnt/c/altera_lite/25.1std/quartus/bin64

Flags

• --win32-quartus - use the Windows Quartus install

• --win32-quartus-path WIN32_QUARTUS_PATH - path to Quartus, overrides $LITEX_WIN32_QUARTUS_PATH
