Hybrid systems like computer-controlled chemical plants are typical safety critical distributed systems. In present practice, the safety of hybrid systems is guaranteed by hazard ...
We describe a method for writing assumption/guarantee specifications of concurrent systems. We also provide a proof rule for reasoning about the composition of these systems. Spec...
We describe an extension to the TLA+ specification language with constructs for writing proofs and a proof environment, called the Proof Manager (PM), to checks those proofs. The ...
Abstract. We describe how the PVS verification system has been used to verify a safety property of a garbage collection algorithm, originally suggested by Ben-Ari. The safety prope...
