Hello I have PCB doesn't contain the spice models of the ICs, how can we replace these models to do EMI/EMC for the PCB?

Hi Alan Alan,

As you indicated ,very often SPICE models are not available from the component vendor. In our Ansys Electronics and Electromagnetics simulation Tools the best way to do this is to simulate your PCB in functional blocks using our Tools either HFSS or SIwave and then using our Ansys Circuit Tool to simulate your whole model. Perhaps break your system down to Analog and Digital sections or by simulating traces only then adding your components in Circuit. This co-simulation approach enables you to leverage all our Ansys Tools in one platform for simulating your one model.

Regards,

Charlotte
