In contrast, S-parameter or AC simulation modes do not provide any information on nonlinearities of circuits. Another factor causing differences may be in the handling of simulation of S-parameter data (I'm not sure if you had any s-parameters in your topology) since the 2 simulators use different algorithms for processing this data. As we know a vector signal consists of both amplitude and phase information. It's right. Place a Variable; declare a variable named astate with the initial value as 1. The tool here is an S-parameter plotter and viewer. Using our S-parameter models in FilterSolutions® from Nuhertz RF inductors models and capture symbols for OrCAD Coilcraft is a member of the E agleware M odel A ccess P artnership program which means that the most up-to-date models are included in each copy of GENESYS. Echoes once again, but with more System. You can extract scattering matrix parameters (S, Y, Z parameters), visualize 3D electromagnetic fields (near- and far-field) and generate ANSYS Full-Wave SPICE models that link to circuit simulations. Avelar, Omar de la Mora & Diego I. S parameters play a dominant role in high speed PCB simulation and verification.
