Dummy surface inserting method for e.g. very large scale integrated circuit, involves processing circuit design by insertion of surface patterns based on insertion hierarchy estimating design hierarchy by processing blocks and units

摘要

The method involves processing integrated circuit design, layer by layer, by selective insertion of patterns of dummy surfaces according to an insertion hierarchy. The insertion hierarchy estimates design hierarchy of the circuit by individual processing of blocks (30) and interconnected units (2) and their interconnection routing. The patterns are selectively established based on methods used for design of the blocks (30). An independent claim is also included for a system of designing an integrated circuit.
