Good day all,
        I am trying to run a simulation in HSpice using the On semi,
mc100lve222_tq52_z.ibs model as the driver.  However I am not getting any
output.  The model was tested in ICX and it passes, so I am under the
assumption that the error is in my calling of the model.  
        The following test file shows how I am calling the IBIS model:

.END 

 If anyone sees any errors or can make any suggestions with regards to their
experiences with this model, your feedback is greatly appreciated.

Thanking you in advance,
