RRAM technology has experienced explosive growth in the last decade, with multiple device structures being developed for a wide range of applications. However, transitioning the technology from the lab into the marketplace requires the development of an accessible and user-friendly design flow, supported by an industry-grade toolchain. In this work, we demonstrate with examples an end-to-end design flow for RRAM-based electronics, from the introduction of a custom RRAM model into our chosen CAD tool to performing layout-versus-schematic and post-layout checks including the RRAM device. We envisage that this step-by-step guide to introducing RRAM into the standard integrated circuit design flow will be a useful reference document for both device developers who wish to benchmark their technologies and circuit designers who wish to experiment with RRAM-enhanced systems.
