Resumen

Descripción

This work presents a Python-based driver for ANSYS HFSS for length matching elements (LME) implemented in Matlab. The driver allows full-wave EM parametric simulation of length matching elements, whose S-parameters are inserted in other circuit simulators, such as ADS, for a complete interconnect validation. Three different LME (i.e., trapezoidal, triangular, and rectangular) are analyzed using the driver in a common high-speed routing scenario. The driver proposed in this work allows verifying that the three LME considered have a similar performance up to 5 GHz, indicating that these LME can be used as mismatch (phase skew) compensation structures in some interfaces within this frequency band, such as USB 3.0, PCIe Gen3 or 1 GBASE Ethernet. On the other hand, the trapezoidal LME shows the best performance for frequencies higher than 5 GHz, with a low impact in the electromagnetic interference (EMI), making it the most recommended for high-speed interfaces with operating frequencies higher than 5 GHz.
