In Ansys Q3D, you can perform PCB parasitic analysis by following these steps:

1. Create/Import the 3D ECAD model of the PCB.
2. Assign boundary conditions
3. Assign signal nets: A net is a collection of touching conductor materials or surfaces. You can assign nets manually or automatically to any conductor ends and classify them as signal, floating, or ground nets.
4. Assign source and sinks on the nets for which the RLGCs are required to be extracted.
5. Setup solutions: Q3D offers three types of solution setups–capacitance, conductance, DC resistance and inductance, and AC resistance and inductance. You can generate RLCG field plots and corresponding E or H field plots.
6. Results: After the simulation model is solved, you can perform post-processing of the obtained results, view the solution data in rectangular tabular format, or plot the results
