We are proud to announce that at this year’s annual model checking contest the model checker TAPAAL defended the silver medal in the category of reachability analysis of P/T nets, this time in competition also with tools that implement parallel state-space exploration, and it was the first tool in the subcategory of deadlock detection. The results were announced on June 23rd, 2015 at the Petri Net conference in Bruxelles. Details about the competition should become soon available at the competition web-page here.

The TAPAAL team is very happy to announce a major upgrade of TAPAAL. The new release of 3.0.0 includes numerous GUI improvements and bug fixes, together with the following selected new features.
GUI and verification support for timed workflow analysis (available under Tool/Workflow analysis) that allow to check for soundness and strong soundness of workflow nets and computing the shortest and longest execution times. A brand new dedicated verification engine verifypn that supports an efficient verification of untimed nets and allows for a quick linear over-approximation test even for timed nets.
