Note:
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. Optimization techniques may further reduce
delays by 0 to 4 ns.
