TRUTH VALUE TABLE INPUT SUPPORTING SYSTEM AND LOGICAL CAD SYSTEM

摘要

PURPOSE: To simplify the truth value table input and to shorten the input working time by recognizing that the input of the mark information stipulated beforehand as the one to express the auxiliary space of logics is the one to show the combination except the defined logical value. ;CONSTITUTION: An input system 12 at a logical simulator includes a means 12A to prepare the interface table based on logical function description information 11 such as a truth value table and an input system 13 at a logical preparing system also includes a means 13A to prepare the interface table based on the information 11. Means 12A and 13A, when the truth value table including the defined logical value and the mark information stipulated beforehand as the one to show the auxiliary space is inputted, recognize the mark information as the one to show the combination except the defined logical value. Thus, the truth value input can be simplified and the input working time can be shortened.;COPYRIGHT: (C)1993,JPO&Japio
