System petri net specification

The high-level synthesis of digital systems, including controllers, DPSs, peripheral components, integrated microsystems, requires intermediate model representation of system specification. A few approaches have been proposed to use Petri nets as an intermediate system representation. The paper discusses essential Petri net properties and concentrates on requirements of the system representation. A new system Petri net text format is presented and it has been developed to support fully wide range of system specifications.
