Efficient Methodology for Modeling Structure of High Speed Long Transmisison Lines

October 19, 2018 Cadence PCB Solutions

A practical approach for accurately modeling high-speed link structures is presented and named as the “cut and stitch” (C&S) methodology. To generate S-parameters for the whole system, C&S first cuts the structure into different parts with different electromagnetic (EM) features and also provides auto-generated ports at the cutting interfaces to do system connection later, then selects the proper EM solver for individual design partition’s modeling, and finally automatically stitches all of the S-parameter models together. Numerical experiments show that the approach can achieve more than one order of the speedup ratio with the acceptable accuracy.
