Note:
*These parameters should be used for estimating device performance. Optimization techniques may further
reduce delays by 0 to 4 ns. Routing delays are for typical designs across worst-case operating conditions. 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.
