VHDL generation from hierarchical Petri net specifications of parallel controllers
Joao Miguel Fernandes, Maciej Adamski, Alberto José Proença · IEE Proceedings - Computers and Digital Techniques · 1997
Parallel controllers can be best specified using a description with a formal support to validate structural and dynamic properties. Petri nets (PNs) can provide an adequate means to model and to animate parallel systems based on the control and data path approach, in a hierarchically structured way. A set of tools was developed to allow formal validation of parallel controllers, based on hierarchical PN-based specifications and to automatically generate RT-level VHDL code. An example of a VLSI chip design, the transputer link adapter, shows the capabilities of this methodology and associated tools.
