# Layout21 

Custom integrated circuit layout.  

[![test](https://github.com/dan-fritchman/Layout21/actions/workflows/test.yml/badge.svg)](https://github.com/dan-fritchman/Layout21/actions/workflows/test.yml)

* A layered suite of layout-data formats, each expressed in the ProtoBuf schema description language. 

* Libraries for compiling from more abstract and terse such expressions into more-detailed. 

* Exchange with industry-standard formats such as [GDSII](./gds21) and [LEF](./lef21).

Each of the internally-defined `layout21` compilers, parsers and generators are implemented in [Rust](https://www.rust-lang.org/). Cross-language compatibility of the underlying [ProtoBuf](https://developers.google.com/protocol-buffers)-based data schema allows for usage in most other popular languages. 

Like most large Rust projects `layout21` is a multi-crate workspace. Some internal crates are publicly available through [crates.io](https://crates.io). The "top-level" [layout21](./layout21) crate includes dependencies on all, and is the easiest entry-point for using all `layout21` functionality. In `layout21`'s namespace and in documentation most child-crates are referred to by their suffixes, i.e. `layout21::raw`.
