SiliconCompiler is a modular hardware build system ("make for silicon"). The project philosophy is to "make the complex possible while keeping the simple simple".

SiliconCompiler is available as wheel packages on PyPI for macOS, Windows andLinux platforms. For working Python 3.9-3.13 environment, just use pip.

pip install --upgrade siliconcompiler

Converting RTL into DRC clean GDS takes 13 lines of simple Python code.

• Ease-of-use: Programmable with a simplePython API
• Portability: Powerful dynamic JSONschema supports ASIC and FPGA design and simulation
• Speed: Flowgraphexecution model enables cloud scale execution.
• Friction-less:Remote execution model enables "zero install" compilation
• Modularity:Tool abstraction layer makes it easy to add/port new tools to the project.
• Provenance:Compilation manifests created automatically during execution.
• Documented: An extensive set of auto-generated high qualityreference documents.
• In-use: Actively used by Zero ASIC for commercial tapeouts at advanced process nodes.
