METHOD FOR OUTPUTTING LOGICAL CIRCUIT DIAGRAM

PURPOSE:To easily consider loading information to be required at the time of checking or changing logic by executing the gate number calculating processor of the like of a logical circuit diagram information file to calculate loading information and adding the loading information to the above information file. CONSTITUTION:In this logical circuit diagram outputting method, information relating to restricting factors for the physical formation of a logical circuit is added to a logical circuit diagram. Namely number of gates calculating processing 100, delay time calculating processing 120 and power consumption calculating processing 130 are applied to a logical circuit stoked in a logical circuit diagram information file 100 and a logical circuit diagram information file 140 to which loading information to be required at the time of forming a logical circuit on an LSI chip is formed and outputted. Since information relating to physical restricting factors can be also displayed simultaneously with the output of an easily observable graphic, the satisfaction of physical restricting conditions to be required at the time of checking or changing the logical circuit can be checked and logic can easily be checked of changed.
