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

ABSTRACT 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.
