|
Various tasks in formal verification and synthesis rely on efficient techniques to remove existential quantifiers from formulas in First Order Logic. Additionally, modern quantifier elimination approaches are able to produce Skolem functions witnessing existential quantifiers. I present AE-VAL, a decision procedure for Linear Rational Arithmetic that enumerates models for quantified formulas and automatically constructs Skolem functions. In the talk, I demonstrate the use of AE-VAL for the tasks of "Realizability Checking and Synthesis of Contracts" and "Automatic Discovery of Simulation Relations". |
