SiliconCompiler is a modular Python-based hardware build system that automates the flow from RTL source code (Verilog, VHDL, Chisel, etc.) through synthesis, place-and-route, and verification to GDSII, supporting both ASIC and FPGA targets. It orchestrates open-source and commercial EDA tools (Yosys, OpenROAD, Verilator, Vivado, Cadence, Synopsys) with pluggable PDKs, flows, and remote/cloud execution.

Use cases

• compile RTL to GDS for an ASIC
• build an FPGA bitstream from Verilog
• automate my chip design flow instead of makefiles
• run synthesis and place-and-route with open source tools
• lint my Verilog without installing EDA tools
• run hardware builds in CI on every commit
• try ASIC compilation in the cloud without installing tools
• simulate my design with Verilator or Icarus

When to choose

• you want a scriptable, Python-based alternative to hand-written Makefiles for chip or FPGA builds
• you need to mix open-source and commercial EDA tools in one automated flow
• you want to try hardware compilation quickly via remote execution or Docker without installing EDA tools
• you need reproducible, CI-friendly hardware builds with packaged PDKs like sky130 or gf180

When to avoid

• you need a GUI-driven EDA workflow with interactive layout editing
• your flow depends on proprietary foundry PDKs you cannot package or share
• you only need simple FPGA synthesis where vendor IDEs (Vivado, Quartus) already suffice
• you work primarily on Windows with local tool execution, which is unsupported
