Dear all, Could somebody explain how the value of Vdiff is defined? Does Vdiff=250mV mean +-125mV or +-250mV! According the IBIS cookbook-v4, at page 73 where it says "For example, an active-high buffer with a vdiff of 100 mV will be considered high if the non-inverting pin is at least 100 mV above the inverting pin. " I would expect it to be defined as +-125mV but one our SI tool provider is defining it at +-250mV?
