Abstract
The digital simulation package described in this paper has the following main features: • - Circuits can be specified and simulated at three levels of abstraction: gate level, transition table level, and register transfer level. Specification is mostly by a special purpose language. • - A specification expressed at one level of abstraction may be replaced by another at a different level. • - Descriptions developed by the user become library modules. • - The program works on many popular computers and does not require graphics. It is written in Pascal and porting it to other systems should be easy. The package was designed mainly for teaching and for use on microcomputers. This is reflected in the syntax of the hardware description language, the friendliness of the user interface, and certain diffences in comparison with production cad tools. The speed of simulation is limited. An extension of hard allowing it to drive external hardware circuits is now under development. Several examples of hard are given.
