Accelerator Series FPGAs – ACT 3 Family
A1425A, A14V25A Timing Characteristics
(Worst-Case Commercial Conditions, VCC = 4.75 V, TJ = 70°C)
1
Notes:
1.
VCC = 3.0 V for 3.3V specifications.
2.
For dual-module macros, use tPD + tRD1 + tPDn , tCO + tRD1 + tPDn or tPD1 + tRD1 + tSUD , whichever is appropriate.
3.
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.
