Dennis et al,
I have written a memory model with tri-state outputs using the VITAL2000
memory package. I get the correct results but, when changing the output
values to or from 'Z' AddPathDelay seems to choose the tr01 or tr10
delay values. This is true whether or not I enable OutputRetainFlag.
It appears from the code for VitalMemoryCalcDelay that in order to use a
Z delay, the constant Delay must be of type VitalDelayType01ZX. This
seems odd to me. Was it intentional? If so, could someone please
explain the intent behind it?
Thanks,
