Abstract

Using interactive simulation preserves the experimental nature of digital-logic and computer-design laboratories. Components providing special features and design challenges extend a simulator to enhance this mode of simulation. These special components provide powerful diagnostic tools, multi-element displays, and animated devices.The basic simulator uses three-level signals and is event driven. Over forty components form the standard complement of elements. These include primitive gates and functionally-implemented multiplexers, decoders, registers, counters, RAM's and ROM's.The normal simulation mode provides keyboard interaction for changing network excitations by switch toggling and pulser activation. Periodic clock of unlimited duration are also included. This combination provides a motivating setting for experimenting with and solving complex design problems.
