ProTR: a tool for real-time systems development

Real time systems is an application area where digital computer usage has grown significantly in the last decade. It has done so in parallel with the development of techniques and the proposition of software engineering approaches aiming at an effective and economical way of producing software. Real time applications present features distinct from other applications and impose suitable techniques and models for software development. One of the most well-known methodologies, "Structured Development for Real-time Systems", by Ward and Mellor (1985), was used as the model for prototype generation in a real-time prototyping system (ProTR); ProTR is described and its application is shown through an example.<>
