IBIS allows v-t curves to be generated for different output loads. Good IBIS models generally do this. Is this what you are asking about? -----Original Message----- From: si-list-bounce@xxxxxxxxxxxxx [mailto:si-list-bounce@xxxxxxxxxxxxx]On Behalf Of TerenceHsieh@xxxxxxxxxxxx Sent: Wednesday, December 01, 2004 2:52 AM To: si-list@xxxxxxxxxxxxx Subject: [SI-LIST] multiple pairs of waveform in IBIS Dear all If we use multiple pairs of waveform table in IBIS, it's behavioral model could be more accurate and covers a wide range of load conditions. Where could I find the documents about the detail interpretation of spice for modeling IBIS with multiple pairs of waveform?
