Instructions

Run the simulation with post processing as shown here.

Run simulation and output to default location
gerber2ems -a
  • Results of post processing should be stored in ems/results/*.csv.
  • Graphs should be stored in ems/graphs/*.png.
  • The ems folder is controlled by the --output argument to gerbv which is explained here

Post processed results

  • S parameters are calculated for all excited ports.
  • Impedance of signal trace or differential pair is calculated.
