Note:

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.
