2.9.1.3 PCB Trace Models

(Ask a Question)

The PCB file must be converted into a compatible format of simulator software. For example, the .HYP file format of PCB is required to be simulated in Hyperlynx, and .SPD file format of PCB is required to be simulated in Sigrity. Once the PCB file is loaded in the simulation tool, the stack-up that matches the PCB stack-up must be checked. The dielectric constant, Dk and dissipation factor, and Df of PCB material must be defined. The tool extracts incorrect models, if the points are not defined properly.

The SerDes traces must be identified and ports on both the sides of the traces need to be assigned. The S-parameter models of traces should be extracted. The following tools can be used to extract S-parameter models of PCB traces:

Agilents ADS
Mentors Hyperlynx
Sigritys PowerSI

Important: It is not mandatory to use the mentioned tools, many other tools are available in the market which can extract S-parameter models.
