In this paper we introduce Echidna, a hybrid schematic/ text-based language for describing PCB circuit schematics. Echidna allows designers to use high-level programming con- structs to describe schematics, supports modular, reusable design components with well-defined interfaces, and provides for complex parameterization of those modules. Echidna deeply integrates a high-level programming language into a schematic-based design flow. The designer can describe schematics in code, as a schematic, or as a seamless combination of the two. We demonstrate its usefulness with several case studies.
