OpenROAD-flow-scripts (ORFS) is a fully autonomous, RTL-GDSII flow for rapid architecture and design space exploration, early prediction of QoR and detailed physical design implementation. However, ORFS also enables manual intervention for finer user control of individual flow stages through Tcl commands and Python APIs.

Document for detailed local installation steps found here.

To ease dependency installation issues, ORFS uses docker images. Docker image includes ORFS binaries, applications as well as all required dependencies. All of the flow tools are encapsulated inside the container image.

If Docker is not installed already, install latest docker tool based on OS from here.

To manage docker as non-root user and verify that you can run docker commands without sudo must complete steps from here.

Document for detailed steps on docker based installation found here.
