This 10-minute talk from the Linux Foundation provides an overview of how to design custom silicon using the same Bazel workflow typically used for software development. Discover how the hdl/bazel_rules_hdl repository enables hardware description language (HDL) development within the Bazel build system. Ethan Moon Mahintorabi presents this introduction at BazelCon 2021, connecting software engineering practices to silicon design. Explore various open-source resources including the Open MPW Shuttle Program, The-OpenROAD-Project, YosysHQ, KLayout, and Google/xls that support custom silicon development. Learn how these tools can help bridge the gap between software and hardware development workflows.
