Analysing PEARL Programs for Timely Schedulability and Executability

Abstract

PEARL is a widely-used, standardised, industrial process-control programming language. The programs, that are written in PEARL, are typically expected to operate in a predictable, timely, reliable manner. Developing such programs is no easy task. Yet, with the invent of the experimental programming language Real-Time Euclid and its schedulability analyser, a tool that is used to predict whether real-time software will adhere to its critical timing constraints, it has been demonstrated that this task may be made considerably easier.
