ABSTRACT:
An interactive graphic editing system for designing a semiconductor integrated circuit includes an attribute data base storage unit for storage of attributes of editing objects necessary for simulating characteristics of the semiconductor integrated circuit being designed, and an editing unit for enabling the editing objects to be manipulated and for fetching data from the attribute data base storage unit on selection of the editing objects as to whether or not the attributes for the selected editing objects can be set. The graphic editing system informs an operator as to feasibility of the selected attribute setting by making an inquiry at the attribute data base on selection of the editing objects as to whether or not the attributes concerning the selected editing objects can be set and displays an attribute setting menu for editing objects for which attributes can be set without displaying the attribute setting menu for designing objects for which attributes cannot be set.
