Notes:
1. For dual-module macros, use tPD + tRD1 + tPDn, tCO + tRD1 + tPDn, or tPD1 + tRD1 + tSUD, whichever is appropriate.
2. 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.
3. Optimization techniques may further reduce delays by 0 to 4ns.
