OpenLane makes a lot of use of OpenROAD. This is a project funded by DARPA to develop open source ASIC tooling.

I love the layout of the course, you did a perfect job Matt. Building up the foundation and then getting into the depths of it. Having everything lined up. I love the walkthroughs at the end of each section.
