Abstract

A system for interactive design and simulation of an electronic circuit allowing a user to design a circuit by graphical entry and to view full or partial simulation and design results simultaneously, on a single display window. The user is able to define the form of a display of speed, delay, loading, symbols, simulation input and/or output values on each node and any path of the design. Simulation may be user-defined or other process time. The user is further able to view any information relevant to any object in the design at any level of design abstraction, and is able to view multiple levels of design abstraction simultaneously and to display information common to the various representations.
