INTERFACE DESIGN AND CONTROLLER SYNTHESIS OF DIGITAL-SYSTEMS IN AN OBJECT-ORIENTED ENVIRONMENT

The paper proposes a design environment over an object database system for representation and synthesis of circuits. Circuits in the underly ing object oriented environment are modeled as classes. An interface d escription of the circuit class is maintained as a part of the class t o facilitate its reuse. A scheme for synthesizing controller in such a n environment is presented. The controller of a circuit is synthesized from the local controllers of the modules present in its datapath. Pe tri net model has been adopted to represent the controller.
