A formal design notation for real-time systems
Miguel Felder, Mauro Pezzè · ACM Transactions on Software Engineering and Methodology · 2002
The development of real-time systems is based on a variety of different methods and notations. Despite the purported benefits of formal methods, informal techniques still play a predominant role in current industrial practice. Formal and informal methods have been combined in various ways to smoothly introduce formal methods in industrial practice. The combination of real-time structured analysis (SA-RT) with Petri nets is among the most popular approaches, but has been applied only to requirements specifications. This paper extends SA-RT to specifications of the detailed design of embedded real-time systems, and combines the proposed notation with Petri nets.
