Towards Dependable Development Tools for Embedded Systems: A Case Study in Software Verification

Uwe Petermann, University of Applied Sciences Leipzig, Germany

This case study describes the specification and formal verification of the key part of TeCOM, a development tool for the design of open loop programmable control developed at the University of Applied Sciences in Leipzig. TeCOM translates the high-level representation of an open loop programmable control into a machine executable instruction list. The produced instruction list has to exhibit the same behavior as suggested by the high-level representation. We discuss the following steps of the case study: characterization of the correctness requirements, design of a verification strategy, and the correctness proof.
