FUNCTION DESIGN ASSITING DEVICE AND FUNCTION DESIGNING METHOD

摘要

PURPOSE: To provide the function design assisting device which can easily know the concrete contents of test facilitation design by confirming test easiness on a function diagram representing the operation function of a logic circuit with a figure, a table, or characters. ;CONSTITUTION: A function diagram editor part 4 generates the function diagram on the basis of information which is inputted from an input device 1. A function diagram check part 5 tests whether or not the function diagram has contradiction and displays the test result on a display device 2. Here, when the function diagram has the contradiction, the function diagram editor part 4 corrects the function diagram and then the function diagram check part 5 tests whether or not the function diagram has contradiction again. Then when the function diagram has no contradiction, a testability check part 6 confirms the easiness of the function diagram and displays the confirmation result on the display device 2. When the test easiness is good, a function description language conversion part 7 generates a function description language from the function diagram.;COPYRIGHT: (C)1995,JPO
