For some parallel and PMOS only devices, the starting current may be higher then the ending current in the table. This currently produces an ERROR, and some parsers will not allow the device to be processed. This BUG suggests changing the message to a WARNING. The current report is shown below. Checking bug65.ibs for IBIS 3.2 Compatibility...
