VLSIR - A Modular Framework for Programming Analog & Custom Circuits & Layouts

Abstract

We present VLSIR, a modular and fully open-source framework for programming analog and custom circuits and layouts. VLSIR is centered around a protobuf-defined design database. It features high-productivity front-ends for hardware description ("circuit programming"), simulation, and custom layout programming, designed to be amenable to both human designers and automation.
