IBIS - Why are Vmeas/Cref/Rref/Vref not included for the HSTL1_I model in the Virtex IBIS file?


There is not a value given for the Vmeas/Cref/Rref/Vref parameters in the HSTL1_I model in the Virtex IBIS file.


These parameters are used in the timing simulation of output signals based on their loading. The HSTL1_I is an input model only, so these output timing parameters do not apply.
