Patent ID: 7412675

Claim:
A method of computing electrical parameters of elements to be created in an integrated circuit, comprising: creating a database that defines elements to be created in a layout of the integrated circuit, the database defining a number of cells that define circuit elements that may be repeated in the layout; computing the electrical parameters for each element in a cell to form a circuit representation, and using the circuit representations computed for each circuit element at each placement of the corresponding cells; and rearranging the circuit representations for all cells in the database into a format suitable for circuit analysis, wherein a circuit representation of a cell is adjusted for the interaction of a circuit element in the cell with a circuit element in another cell, and wherein the circuit representation is adjusted by promoting the element of the cell into the cell having the interacting element and computing the electrical parameters of the promoted element while adjusting for the interaction, or by creating a copy of the interacting elements of the other cell within the cell in which the electrical parameters are being computed.
