Case studies in the hybrid process algebra HyPA

HyPA is an algebraic theory based on the classical process algebra Algebra of Communicating Processes (ACP) for the specification and analysis of hybrid systems. We have the idea that HyPA is also well suited for addressing various aspects of digital embedded systems including hardware, software and concurrency, as well as mixed-signal designs. To show that HyPA is useful for the specification and analysis of hybrid systems and that our idea is correct, we illustrate the use of HyPA with some case studies: a point-to-point communication, a thermostat, a positive-edge-triggered D flip flop, and a small part of a mixed-signal fuzzy controller.
