New page

LibreLane is the successor of OpenLane V2, rewritten as python scripts for the VLSI design flow using open source tools.

== Setup LibreLane ==

[https://librelane.readthedocs.io/en/latest/getting_started/migrants/index.html Read this] if interested to migrate from OpenLane.

This is a Nix based installation (preferred).
Clone the repository and run the nix shell. The first time will take time as everything is pulled in and set up.

git clone https://github.com/librelane/librelane

cd librelane
nix-shell shell.nix

If you run into python test errors, you may have to edit the default.nix, the line with
doCheck = true;
to:
doCheck = false;

Run a test example to verify all works:
mkdir my_designs
cd my_designs/
librelane --run-example spm
