A text is generated on the origin of this temporary area POL (Step 2304).
The coordinates of origin of a temporary area POL for processing the graphic corresponding to the temporary area SVP are extracted from the graphic table included in the data base-storing area, according to the adopted corresponding temporary area SVP (Step 2303). In this case, a temporary area SVP first detected in the correspondence table is adopted because a plurality of temporary areas SVPs exist in the correspondence table of one temporary area SIG. A temporary area SVP for correspondingly processing the signal taken out from the correspondence table is extracted (Step 2302). 23, a first signal of the connection table is taken out from a temporary area SIG for processing a signal name taken out from the connection table (Step 2301). 23 is a flow chart showing the procedure of the text generating method by the conventional layout editor.
This kind of conventional text generating method has a data base-storing area including a graphic table for storing graphical information, a connection table for storing connection information, a correspondence table for storing the correspondence between the connection information and the graphical information, in the net-driven layout data base.įIG. A text is generally generated by user's input depending on the necessity in case of examining the wiring configuration with reference to the halfway results, or executing a work to be continued to another layout area, a layout-circuit comparison in the verification, or data modification.
In the other words, the tool itself needs no text and thereafter it has no function of text generation. Generally, a net-driven tool is on the assumption of automatic wiring in many cases. The present invention relates to a layout editor and its text generating method, and more particularly to a layout editor and its text generating method for use in semi-custom design or full-custom design in the mask design of IC.
