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.
