In this article, we describe a prototype cosimulation framework using Xyce, GHDL and CocoTB that can be used to analyze digital hardware designs in out-of-nominal environments. We demonstrate current software methods and inspire future work via analysis of an open-source encryption core design. Note that this article is meant as a proof-of-concept to motivate integration of general cosimulation techniques with Xyce, an open-source circuit simulator.
