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 performance.
3. Data applies to macros based on the S-module. Timing parameters for sequential macros constructed from C-modules
can be obtained from the Timer utility.
4. Set-up 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.
5. Delays based on 35 pF loading.
