Patent ID: 7810051

Claim:
A layout method for a layout design of a circuit, to be implemented in a computer, said layout method comprising: carrying out, by the computer, a simulation of the circuit; specifying, with respect to the computer, a maximum current value to flow between terminals of each of elements of the circuit; specifying, with respect to the computer, parameters that determine a shape of each of the elements; and automatically creating and completing, by the computer, a layout of the elements satisfying an electro migration rule, based on the specified maximum current value and shape of each of the elements, wherein the automatically creating and completing the layout comprises: calculating, by the computer, a number of contacts and a wiring width of each of the elements satisfying the electro migration rule; creating, by the computer, the layout of the elements by taking into consideration the number of contacts and the wiring width that are calculated; and carrying out, by the computer, an electro migration judgement so as to confirm whether or not the layout of the elements satisfies the electro migration rule.
