Complete Flow for PCB Design Consideration and Power/Signal Integrity Analysis Based on Broadband Model of Parasitic Elements

A new implementation of a broadband model for the generation of an accurate time-domain description of parasitic elements from frequency-domain electromagnetic (EM) simulator results is here proposed. The model is designed to work simultaneously at low and high frequencies, bypassing EM simulators limitations. A further investigation on the appropriate reference impedance selection during the transformation of data from frequency to time-domain is conducted. The resulting model is validated against measurement and applied to a practical design case, illustrating the operational steps of the novel workflow.
