Abstract
The technique takes advantage of the current ability to increase the density of electronic circuit elements on an integrated circuit chip by combining onto a single chip all of the circuit elements of two or more separate circuits, even when the masks of the separate circuits have been laid out with one or more different design rules, and then connect them to operate together. A mask layout database of one of the circuits at a time is globally changed, with the use of a standard computer software package, to conform it to the design rules of the mask layout database of another circuit, either before or after the circuit databases are combined into a single database.
