An open toolchain for the physical implementation of digital chips, aiming to go from RTL to a GDSII file with no manual intervention. It covers floorplanning and pin placement, power grid, global and detailed placement, clock tree synthesis, global and detailed routing, parasitic extraction and finishing checks. Together with OpenROAD-flow-scripts it works with open process kits such as SKY130 and GF180. It is used in research, teaching and projects that have reached real fabrication. It needs a Linux environment and is built from source or run in Docker.
