Patent ID: 6895344

Claim:
A method for determining a substrate resistance network, comprising: receiving a description of a substrate network, the substrate network comprising a plurality of nodes; identifying a plurality of elements of the substrate network, each element associated with one or more nodes, the plurality of elements comprising a plurality of nwell structures; and repeating the following for each nwell structure of the plurality of nwell structures: dividing the nwell structure to yield a ring geometry and a plurality of area geometries, the plurality of area geometries representing an inward portion of the nwell structure, each area geometry associated with an area resistive element and at least one area coordinate, the ring geometry representing a perimeter portion of the nwell structure; forming a plurality of side geometries from the ring geometry, each side geometry associated with a side resistive element; forming an nwell group comprising the plurality of area geometries associated with the nwell structure in accordance with the area coordinates; and determining an nwell resistance network for each nwell group using the area resistive elements and the side resistive elements.
