Abstract
A logical simulation system for a data processor includes a logic circuit model constituting a part of logic of the data processor to be tested with basic logic elements capable of calculating operation processes in detail, a logic function model describing functional operations of the other logic of the data processor in terms of machine word instructions for executing functional operations of the other logic at a high speed, and a communication routine for performing data transfer between both the models and controlling the execution of instructions. The processings for executing individual instructions contained in a test program are shared between both the models through the medium of the communication routine.
