Verification of an audio control protocol within real time process algebra

In [4], Bosscher, Polak and Vaandrager have formally analyzed, based on weak timed forward simulation by using the timed I/O automata, a simple version of an audio control protocol developed by Philips for the physical layer of an interface bus that connects the various devices of some stereo equipment. The protocol, which uses Manchester encoding, has to deal with a significant uncertainty in the timing events due to both hardware and software constraints. It is a very nice example and therefore it has been suggested as a benchmark for other researchers to test their methods on, just as the Cizt and Mouse example of [lo] and the Gas Burner example of [ 143.
