A Petri-net-based approach to real-time program analysis

Abstract

We propose to extend existing Petri-net-based tools for concurrency analysis to real-time analysis. The goal is to create a fully automated system, which starts from code in a higher level language for real-time programming, and answers programmers' queries about timing properties of the code. The key difficulty with all reachability-based approaches is that the state space quickly becomes intractably large. To circumvent this state explosion problem, we propose using a combination of several heuristics for model reduction and state space reduction that have been effective for untimed concurrency analysis.<>
