Abstract:
1. A method comprising: providing a plurality of pins routed together on a net, wherein each pin has a current value; calculating a current requirement for each track segment of the net; determining a track width for each track segment using a current density function; and performing an automated routing of a first track segment of the net, wherein the automatically routed first track segment has a track width as previously determined using the current density function, and the calculating a current requirement for each track segment of the net comprises: providing a first pin having a first current value connected to a second track segment of the net; providing a second pin having a second current value connected to a third track segment of the net, wherein the second and third track segments are connected; setting the first current value as a current requirement for the second track segment; setting the second current value as a current requirement for the third track segment; providing a fourth segment connecting to the second and third track segments; and setting a sum of the first and second current values as a current requirement for the fourth track segment.
