Abstract

We developed an original method to synthesize monitors from declarative specifications written in the PSL standard. Monitors observe sequences of values on their input signals, and check their conformance to a specified temporal expression. Our method implements both the weak and strong versions of PSL FL operators, and has been proven correct using the PVS theorem prover. This paper discusses the salient aspects of the proof of our prototype implementation for on-line design verification
