Abstract: A design support apparatus includes a memory and a processor coupled to the memory. The processor executes a process including: for each of the plurality of first cells, selecting the second cell connected via the wire to the identified another first cell, the another first cell being included in the identified other first cells, when the identified another first cell is included in the identified other first cells; for each of the plurality of first cells, registering, in the first information, information that the first cell and the selected second cell are connected via the wire when the first cell and the selected second cell satisfy predetermined design rules; and copying the selected second cell, and registering, in the first information, information that the copied second cell and the first cell are connected via the wire when the predetermined design rules are not satisfied.

Abstract: A graphic object designating apparatus for designating a graphic object to be edited among graphic objects present in an edit area of a graphics editing system according to the position of a mouse cursor. The apparatus includes an object managing section that manages object information and the mouse cursor position, and a rule storage section in which assignments of key entries for indicating a direction in which the mouse cursor should move and for designating an object directly under the mouse cursor have previously been stored as rules. A trigger processing section generates a mouse cursor moving trigger or an object designating trigger according to the key entries and the rules. An object designating section moves the mouse cursor or designates the object to be edited on the basis of the object information and the triggers. The apparatus allows an operator to designate a desired object easily within the object display screen.

Abstract: The present invention as disclosed hereby is to provide a drawing input apparatus, drawing input program and drawing input method. The drawing input apparatus comprising: a drawing inputting/editing portion adapted to input or edit drawing data; a rule information storing portion adapted to store therein rule information defining rules for inputting or editing the drawing data; and a rule checking portion adapted to check by using the rule information a part which is present in the drawing data and which is modified based on a predetermined operation on the condition that said drawing inputting/editing portion executes such a predetermined operation.

Abstract: A logical circuit is configured by connecting a plurality of circuit blocks. A driving ability value computation unit computes a driving ability value required for a target circuit block based on a delay rate of the circuit block indicating a rate of delay of a signal traveling in the circuit block by a load capacity value provided by the circuit block, a driving ability value of a prior stage circuit block prior to the target circuit block, and a load capacity value provided for the target circuit block. A change unit changes the specification of the device used in the target circuit block based on the driving ability value obtained by the driving ability value computation unit.
