## What it is
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
