SYSTEM FOR CREATING LAYOUT AND WIRING DIAGRAMS FOR INTEGRATED CIRCUIT (IC), METHOD FOR CREATING FLAT PLACED LAYOUT, AND COMPUTER PROGRAM PRODUCT (FAST ROUTING OF CUSTOM MACRO)

摘要

PROBLEM TO BE SOLVED: To provide fast routing of custom macros. SOLUTION: A system for creating layout and wiring diagrams for an integrated circuit (IC) includes a placement engine configured to receive a hierarchical schematic and to create a placed layout. The system also includes a flat layout engine configured to receive the hierarchical schematic and to create a flat layout, and a back annotation engine coupled to the placement engine and the flat layout engine, wherein the back annotation engine is configured to receive the hierarchical placed layout and the flat unplaced layout and to create a flat placed layout there from.
