OpenROAD is an open-source application implementing a unified RTL-to-GDSII flow for digital chip design, covering synthesis through floorplanning, placement, clock tree synthesis, routing, and finishing. It aims for autonomous, no-human-in-loop physical design with 24-hour turnaround from RTL to final layout.

Use cases

• run an RTL-to-GDSII flow for digital IC design
• perform floorplanning, placement, and routing for a chip layout
• do static timing analysis on a netlist
• explore physical design implementations without commercial EDA licenses
• generate GDSII final layout from Verilog and library files
• automate no-human-in-loop chip implementation

When to choose

• you need an open-source alternative to commercial physical design tools
• you want rapid RTL-to-GDSII turnaround for design exploration
• you are doing academic or research ASIC/IC design
• you need scripting-driven, automated place-and-route with Tcl

When to avoid

• you need analog or mixed-signal design tools
• you require certified production sign-off flows with vendor support
• you are designing FPGAs rather than ASICs
• you need a GUI-first interactive layout editor
