Feature Based Coverage Analysis of AMS Circuits
Antara Ain, Akshay Mambakam, Pallab Dasgupta · 2018
Coverage analysis for Analog and Mixed-Signal (AMS) behaviors involves exploring continuous state spaces defined by real valued artifacts. For example, coverage of analog features such as settling time, peak overshoot, etc., entails not only finding whether we have seen such behaviors, but also whether we have covered the range of values of such features (including the extremal values). Thus it is simplistic to lift the notion of assertion based functional coverage from the digital domain into the AMS domain - rather we need to address coverage in the value and time domains. In this paper we propose a methodology for feature based coverage analysis of AMS circuits.
