    Protel for SI Simulation

    P*otel for SI Simulation Regarding the accuracy of the simulator, you may want to ask their technical support to provide any benchmark report to you. However, keep in mind, that is just a simulator, the simulation results depend on both the model and the simulator, sometimes, if the model is...

    Ansoft - Differential feed

    Let me try to continue the discussion and add what my understanding, meanwhile, I also have a question. 1) a voltage potential is the integration of E field from point A to point B. Under static field condition, the integration value has nothing to do with the integral path. However, at high...

    EMC (Electromagnetic Compatibility)

    If we review the PCB board structure, we can see there are two categories: One is with the surface routed traces, one is with the edge of the PCB board. For the surface traces, we can think about there is a line current radiator above a ground plane. We can calculate the radiation. This is...

    HFSS Port Termination Question

    I agree. You can still simulate with 20 ports defined, after you got 20 ports S parameter, you can then use matrix computation technology to terminate the 10 ports that you don't want. S parameter is linear relationship, find out the termination condition, you will derive the new S parameter...
