Prometheus is known, among other things, as the Greek god of foresight. In IC design and test, a little foresight can pay large dividends later. This is a tool made by IC designers for IC designers, based on decades of experience. It solves many of the most common problems encountered in design and testing of analog-mixed signal integrated circuits by centralizing the information that fully describes the state of your system. This centralization provides many advantages with regard to synchronization, reproducibility, traceability, and usability. It is all handled through a graphical interface and accompanying API that boosts productivity and increases insight, enabling rapid test automation and multi-user collaboration.
