Resonance-aware methodology for system level power distribution network co-design

Power delivery network (PDN) design continues to be a major challenge because it demands a good portion of available silicon, package, and board routing resources. In this paper, we outline a frequency and time domain co-design flow that uses frequency domain results to construct time domain input vectors, resulting in a resonance aware time domain analyses flow that can highlight low and mid frequency behaviors dominated by board and package components and parasitics.
