Transmission Line Simulation in EMX

Hello everyone,

Can some one help me in how to do the transmission line (both Single ended and Differential) simulation in EMX ? I couldn't get any document from cadence either explaining the same.

This topic has pointers to documentation.

The really short answer is you create a layout use pins to define where ports will be and then EMX generates s-parameters. If you have something like a differential transmission line you will end up with a 4-port network. You can pull that into a spectre simulation with the nport device or load the file into something like python with scikit-rf and plot the single ended s-parameters and also convert to a mixed mode network where you can plot differential-to-differential, common-mode-to-common-mode, or differential-to-common-mode s-parameters.
