Abstract
A method of determining widths and/or routes of I/O power routes between one or more power distribution networks and a plurality of I/O circuits based on IR chop, electromigration, and electrostatic discharge electrical requirements. The method includes initially routing the I/O power routes and then iteratively analyzing the I/O power routes and iteratively incrementing the width of each power route that fails one or more of the electrical requirements until all power routes meet all electrical requirements. Once all power routes meet the electrical requirements, power routing is performed again to re-route any power routes as necessary to accommodate their wider widths. The method may be implemented in a system that includes a power routing tool, an electrical analysis tool, and a tool integrator tat implements an integrated power routing algorithm.
