This September 21-24th, the 59th annual RSSI C&S Exhibition, in conjunction with Railway Interchange, was held in the Minneapolis Convention Center. Prover participated with a booth at the exhibition and a presentation at the AREMA conference. As always, we had a great time and enjoyed catching up with many long-term customers and partners, as well as making some interesting new connections. A big thank you to the entire RSSI team for again making the exhibition a great success!
At our booth we had the opportunity to demonstrate our Prover iLock tool suite; a desktop solution for automated development of rail control software. It covers formal safety verification, simulation-based testing, documentation and code generation, based on generic requirement specifications formalized in the PiSPEC language. It is a unique, vendor-neutral, development solution that can be adapted to a variety of signaling platforms and principles, and already comes with support for many of the most popular interlocking platforms, such as ElectroLogIXS, Microlok, VPI and Westrace.
Tuesday morning, Jesper Carlström presented his paper on the Signaling Modernization at Stockholm Metro. His presentation included an overview of the signaling system of Sweden’s capital, and an introduction to formal safety verification. Stockholm Metro has embraced formal verification and design automation with Prover’s Prover iLock and Prover Certifier tool suites as the most efficient way to manage the development and maintenance of its diverse and complex signaling systems, covering both legacy relay-based systems and more modern computer-based ones.
Looking forward to seeing you at next year’s RSSI C&S Exhibition, in Nashville, TN, June 2-4, 2020!
