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 timi ng pa ra mete rs for the i npu t bu ff er latch ar e defin ed wit h resp ect to the PAD and the D inpu t. Ext erna l
setup/hold timing parameters must accoun t fo r delay f rom an exte rnal PAD signal to the G input s. Del ay from an externa l
PAD signal to the G input subtracts (adds) to the internal setup (hold) time.
5. Delays based on 35 pF loading.
