Abstract: PNs are an efficient methodology for the modeling of discret-event systems. This is due to the existence of a set of analysis techniques available for PNs. We show the advantages on using PN for modeling parallel controllers. We propose some modifications to the usual PN behaviour, for allowing a easier modelation. This article also presents a compiler which generates VHDL code from a PN-based controller specification. Finally, an example is considered and analysed.
