Patent ID: 7228521

Claim:
A system comprising: a first programmable logic device segmented into a first plurality of regions having a selected number of regions including at least a first defective region; a first code assigned to the first programmable logic device, the first code indicating the first defective region of the first programmable logic device; a first guide file stored on a computer-readable medium and retrieved in response to the first code, the first guide file blocking the first defective region from being used during placement and routing of the first programmable logic device; and a second programmable logic device segmented into a second plurality of regions having the selected number of regions including at least a second defective region equivalent to the first defective region of the first programmable logic device, wherein the first code is further associated with the second programmable logic device indicating the second defective region, wherein the first guide file further blocks the second defective region during placement and routine of the second programmable logic device; and wherein the first programmable logic device is segmented into the selected number of regions according to at least one of logical segmentation of the first programmable logic device and physical segmentation of the first programmable logic device.
