Formal analysis of functional and non-functional requirements is crucial inautomotive systems. The behaviors of those systems often rely on complexdynamics as well as on stochastic behaviors. We have proposed a probabilisticextension of Clock Constraint Specification Language, called PrCCSL,forspecification of (non)-functional requirements and proved the correctness ofrequirements by mapping the semantics of the specifications into UPPAAL models.Previous work is extended in this paper by including an extension of PrCCSL,called PrCCSL*, for specification of stochastic and dynamic system behaviors,as well as complex requirements related to multiple events. To formally analyzethe system behaviors/requirements specified in PrCCSL*, the PrCCSL*specifications are translated into stochastic UPPAAL models for formalverification. We implement an automatic translation tool, namely ProTL, whichcan also perform formal analysis on PrCCSL* specifications using UPPAAL-SMC asan analysis backend. Our approach is demonstrated on two automotive systemscase studies.
