Routing delays are for typical designs across worst-case operating conditions. These parameters should be used for estimating device
Optimization techniques may further reduce delays by 0 to 4 ns.
For dual-module macros, use t
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.
