| Abstract |
This paper presents an algorithm to support the PCB design process by automatically extracting its parasitic components in the critical path from a common EDA tool. An algorithm reads the board file from an EDA tool and feeds the information to the open source programs FastHenry2 and FasterCap. These programs are used for the extraction of frequency-dependent resistances, self and mutual inductances of the PCB tracks as well as the capacitances between those tracks. By augmenting the extraction process by automatically finding the critical path in any given power converter, the extraction procedure can be sped-up significantly and made more user-friendly. Especially in fast-switching applications this approach helps to reduce the usually needed design iterations by knowing the effect of differently routed PCBs. The accuracy of the calculated parasitics is verified by experimental results. |
