Tool/software:
I looked at the model you sent, but it seems that the model will not work because only the two pins EN_UVLO and CLK are mapped except for the power pin.
For a typical IBIS model, there must be a model within each pin, the model name mapped to each pin, and the actual model.
I want to get the Power Switching waveform coming from sw1, sw2.
Please double-check if you have an IBIS file or PSPICE file to run the relevant simulation.
