Prover PSL, the leading model checker used for formal verification in the rail and metro signaling domain, is now even faster. The performance release Prover PSL 5.10 brings 28 % increased speed on average, measured on our test cases from the rail and metro domain. We know of no model checker that performs better!
We have also introduced a new kind of parallelization of the powerful model checking strategy IC3, leading to substantial reductions in proof times. We saw runtime reduction from 111 seconds to just 1 second in one case, and an average speedup factor of 3.2 on other cases we measured.
We are proud to provide you with the best tools possible. Please let us know what you think when you have tried Prover PSL 5.10.

Starting in May 2025, Prover will lead a 24-month project to develop standardized approval methods for modular digital interlockings. Using formal verification and automated testing, the project supports EULYNX and Europe’s Rail goals for interoperable, vendor-independent signaling. Partners include DLR and ESE Engineering.
Prover is partnering with Eiffage Énergie Systèmes on the Villeneuve Demain project, delivering railway signaling software for the PAVS system at SIL4 safety level.
Using Prover’s automation tools, the solution ensures EN 50716 compliance, facilitates future maintenance, and enables reuse across similar systems.
Prover will be at Train & Rail, meet us in our booth located at A06:31.
