Patent ID: 8260599

Claim:
A method of designing a physical device using a simulation incorporating separated overlapping functions, wherein said physical device is designed by a method comprising: proposing a design of said device, simulating at least one property of said proposed design; said at least one property describing a characteristic of the functioning of said device; based at least in part on the result of said simulation, proposing a modified design of said device; building said device based on said modified design; said simulation using a plurality of said separated overlapping functions, said separated overlapping functions produced by a method comprising: choosing a plurality of overlapping regions; for each particular region of said plurality of regions, producing and storing in a computer readable medium a plurality of first overlapping functions associated with said particular region, said first plurality of overlapping functions comprising a plurality of overlapping functions having a strong transmission property and a plurality of overlapping functions that do not have said strong transmission property; for each said particular region, on a computer processor taking linear combinations of said associated plurality of first overlapping functions to produce one or more separated overlapping functions associated with said particular region having a related strong transmission property and to produce one or more separated overlapping functions associated with said particular region not having said related strong transmission property.
