Abstract

Designed to overcome the limitations of OpenLane but maintain its signature ease-of-configuration and ease-of-installation, LibreLane is the modular and extensible community-driven successor to the world’s most popular open source EDA flow, reimagining it as not just a flow, but as a customizable ASIC data flow infrastructure. In this talk, we will outline what motivated us to make LibreLane, what it’s currently capable of, and our future development plans, as well as a showcase of both simple and advanced use-cases it enables.
