XC3100:Timing of Direct Connects


XC3100: Direct Connect Timing


Although the direct connects on the faster XC3000 speed grades (-100

and above) are assigned a delay of zero, the direct connect delay on

XC3100 devices is not zero. The timing models differ between the XC3000

and XC3100 families. The non-zero delay in the XC3100 prevents the double

counting of delays elsewhere in the model.
