Introduction

Substrate is a suite of Rust libraries for generating analog/mixed-signal integrated circuits (ICs). Among other things, it provides:

• Parametric netlist/layout generation
• Simulation waveform verification
• Waveform query utilities
• Higher-level layout APIs (grid/track-based, tiling)
• Full control over exported collateral via intermediate representations (IRs)
• Rudimentary caching, multi-threading, error handling
• An ecosystem of simulation, DRC, LVS, and extraction plugins

The primary goal of Substrate is to enable writing generators, or programs that make circuits from a set of specifications.
