In section 3.2 of the 09/15/05 "IBIS MODELING COOKBOOK For IBIS Version 4.0" document, it is stated, "... for each simulation corner, four V-T data sets are generally recommended. Two waveforms - either featuring a load to ground or a relatively low voltage - are generated for the buffer output switching low to high. The other two waveforms - both featuring a load to Vcc or a relatively high voltage - are generated for the buffer output switching high to low." Why do we need two waveforms for each buffer output transition ?
