Abstract

The present invention provides a placement/net wiring processing system using an interactive editor which eases and simplifies operations for placing or moving cells and adding, deleting or modifying wiring.

The placement/net wiring processing system comprises a control means for controlling the execution of a placement and wiring operating and processing program, a display means for displaying placement and wiring information on a screen, an operating and processing means for operating the placement and wiring on the screen, and an information management means for managing the placement and wiring information. The control means copies the program read out thereby and afterwards executes the program. In addition, the control means checks on the placement and wiring processing operated through the program based on execution history information. The display means, when the displayed placement and wiring graphic information is selected and designated sequentially, displays the contents of the placement and wiring graphic information on the screen in accordance with the selection and relates processing-related information associated with placements and wiring which are read out of a storage division and designated by the user to the placement and wiring graphic information for display on the screen.

10. A placement/net wiring processing system as set forth in claim 2, wherein when said displayed placement and wiring graphic information is moved on said editor screen, said operating and processing means designates a direction in which said information is moved.

11. A placement/net wiring processing system as set forth in claim 2, wherein when said placement and wiring graphic information is designated for selection of a copy command, said operating and processing means designates a copying position to thereby copy said placement and wiring graphic information on said editor screen.

12. A placement/net wiring processing system as set forth in claim 2, wherein said control means checks on positional relationships between respective pieces of position information displayed in accordance with a placement rule read out thereby.

13. A placement/net wiring processing system as set forth in claim 2, wherein when said display means displays an area containing a plurality of pieces of placement and wiring graphic information which are placed by operating through a placement and wiring processing program on said editor screen, said display means displays said area with a frame given to a painted-out pattern.

14. A placement/net wiring processing method, comprising the steps of:
