Dear all, I am using Quad XTK to do simulation. When I get the rising delay or falling delay data, those values should be substrated by the Time_TO_VM values from the IBIS model of driver. However, if the IBIS model doesn't include Time_TO_VM data, XTK automatically generates the Time_to_VM values. Does anyone know how these values come from?
