Hspice switch

    Hi

    I'm trying to simulate a HBM model for ESD purposes using Hspice but I
    can't define a switch that will trigger almost instantaneously to
    discharge the "charged" capacitor in that model.

    As I want to simulate only an ESD protection structure with diodes
    (simulatable under Hspice during an ESD event), I want also to observe
    the structure behavior under a waveform such as the one provided by
    the HBM model.

    I appreciate any possible help in this field.

    Best Regards

    Pedro

    Hi
    Use the pulse source at the otherside of the capacitor . It will behave as
    you have a charge cap then connect with a switch.
