Abstract
VeriSiMPL (“very simple”) is a software tool to obtain finite abstractions of Max-Plus-Linear (MPL) models. MPL models (Sect. 2), specified in MATLAB, are abstracted to Labeled Transition Systems (LTS). The LTS abstraction is formally put in relationship with the concrete MPL model via a (bi)simulation relation. The abstraction procedure (Sect. 3) runs in MATLAB and leverages sparse representations, fast manipulations based on vector calculus, and optimized data structures such as Difference-Bound Matrices. LTS abstractions can be exported to structures defined in the PROMELA. This enables the verification of MPL models against temporal specifications within the SPIN model checker (Sect. 4).
