Min Zhang (ECNU) Title: An SMT-based Approach to the Formal Analysis of Clock Constraints Specification Language Abstract: Clock Constraint Specification Language (CCSL) is a formal language used to specify the constraints of clocks. Given a set of clock constraints specified in CCSL, it is desired to know if there exists a schedule that satisfies all the constraints, if the constraints are valid or not, and if the constraints satisfy some expected properties. In this talk, we will explain an SMT-based approach to the formal analysis of Clock Constraints Specification Language. In our approach, we encode CCSL constraints into an SMT problem, and use an SMT solver Z3 to check if there exists a desired schedule to a set of CCSL constraints. We also show how the approach can be used to check the existence of periodic schedules of CCSL constraints.
