CSL (Control Specification Language) is a declarative language for specifying structure and behavior of finite-state systems. We generated a controller for the production cell which was verified using SVE (System Verification Environment), a symbolic model checker. We were able to verify all demanded safety properties, and in addition a substantial set of liveness properties. Model checking also revealed a subtle error in the original design of the controller.
From the good performance results of our experiments we conclude that current techniques can handle realistic problems of complexity well beyond the one represented by the production cell.
