GENERATING PLACE AND ROUTE ABSTRACTS

摘要

Generating place and route abstracts, including: for each of a plurality of cells, generating a wire diagram; for each generated wire diagram, generating, in dependence upon a cell architecture layout, a cell architecture description; for each cell architecture description: generating, in dependence upon the wire diagrams and the cell architecture descriptions, a blockage map specifying locations where the placement of cells or routing structures is prohibited; and generating, in dependence upon the blockage maps and one or more design rules, a library exchange format (‘LEF’) abstract.

1. A method of generating place and route abstracts, the method comprising:
for each of a plurality of cells, generating a wire diagram; for each generated wire diagram, generating, in dependence upon a cell architecture layout, one or more cell architecture descriptions; and for each cell architecture description:
generating, in dependence upon the wire diagrams and the cell architecture descriptions, a blockage map specifying locations where the placement of cells or routing structures is prohibited and a location and a size of one or more input pins and one or more output pins; andgenerating, in dependence upon the blockage maps and one or more design rules, a place and route abstract.
