I just downloaded the software and watched the video on the EM simulation. I am very much a beginner and suspect the problems are user.
I have a simple coplanar design with just a capacitor mounted to it that I want to simulate. When I select the Touchstone file for the capacitor, I notice that only SOT23 and TO92 packages are supported. Selecting SOT23, I am able to run a simulation on the schematic and it seems correct. I am able to adjust the coplanar sections and it effects the simulation as expected.
Next I select the Tools, Create PCB Layout. The software reports “Cannot find a microstrip line.”
For further details on what I am attempting to do, see the following:
