6.1. OpenROAD and Sky130

The OpenROAD-flow is an open-source, technology-independent VLSI toolchain. As of this writing, it has the ability to run synthesis, place-and-route, and drc through various open-source tools.

Hammer has the ability to target the OpenROAD toolchain and the Skywater 130nm PDK. So you can now simply push a button in Chipyard to go from your Chisel design to a somewhat reasonable gds at an example 130-nm node.

Follow these directions in the Chipyard docs to build your own design with OpenROAD and Sky130.
