This short paper summarizes an article published in the Journal of Automated Reasoning. It presents Pardinus, an extension of the popular Kodkod relational model finder with linear temporal logic (including past operators) to simplify the analysis of dynamic systems. Pardinus includes a SAT-based bounded model checking engine and an SMV-based complete model checking engine, both allowing iteration through the different instances (or counterexamples) of a specification. It also supports a decomposed parallel analysis strategy that improves the efficiency of both analysis engines on commodity multi-core machines.
