Abstract
A system and method for limiting the number of simultaneously switching outputs of an integrated circuit chip to at or below a predetermined limit for the chip during a short, predetermined time window by dynamically arbitrating request signals from discrete on-chip logic elements for assignment of output pins according to the priority of the request signals based on the type and intended use of output signals from such elements, and the immediate state of the integrated circuit chip.
