<p>PURPOSE:To recognize the distinction of a selected power voltage by means of a comment and to succesively recognize the occurrence of a selection error by extracting selected power voltage information and comment-outputting power voltage information to a logical simulation result. CONSTITUTION:A power voltage information event extraction block 2 and a power voltage information output block 4 are provided. The power voltage information event extraction block 2 propagates power voltage information to an operation block by power voltage classifications 9 as a power voltage information event 3. A logical value '1' outputted from a power voltage selection block 7 to a wiring 8 is inputted to the operation block by power voltage 9 and the logical value required by the circuit is outputted to wirings 10a-10c based on the power voltage information event 3. The power voltage information block 4 outputs and adds which power voltage is the output result to the logical simulation result as the output comment of power voltage information.</p> |
