Electrical Rule Checking of Integrated Circuits using Satisfiability Modulo Theory
Résumé
We consider the verification of electrical properties of circuits to identify potential violations of electrical design rules, also called Electrical Rule Checking (ERC). We present a general approach based on Satisfiability Modulo Theory (SMT) to verify that these errors cannot occur in a given circuit. We claim that our approach is scalable and more precise than existing analyses, like voltage propagation. We applied these techniques to a specific type of errors, the missing level shifters. On an industrial casestudy, our technique is able to flag 31% of the warnings raised by the voltage propagation analysis as being false alarms.
