Notes:
1.
Routing delays are for typical designs across worst-case operating conditions. These parameters should be used for estimating device
performance. Post-route timing analysis or simulation is required to determine actual worst-case performance. Post-route timing is based
on actual routing delay measurements performed on the device prior to shipment.
2.
Setup times assume fanout of 3. Further derating information can be obtained from the DirectTime Analyzer utility.
3.
Optimization techniques may further reduce delays by 0 to 4 ns.
