Notes:
1. For dual-module macros, use tPD1 + 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. Data applies to macros based on the S-module. Timing parameters for sequential macros constructed from C-modules
can be obtained from the DirectTime Analyzer utility.
4. Setup and hold timing parameters for the Input Buffer Latch are defined with respect to the PAD and the D input. External
setup/hold timing parameters must account for delay from an external PAD signal to the G inputs. Delay from an external
PAD signal to the G input subtracts (adds) to the internal setup (hold) time.
