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.
