Abstract

A method is provided for determining a power noise histogram of a computer system. The computer system includes a skitter circuit with multiple skitter bins, each skitter bin of the multiple skitter bins being connected to a signal line at one or more clock cycles. The method includes: connecting each skitter bin to an individual counter circuit; and incrementing a counter when the respective skitter bin is enabled.
