Notes:
1. 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.
2. Set-up times assume fanout of 3. Further testing information can be obtained from the Timer utility.
3. The hold time for the DFME1A macro may be greater than 0 ns. Use the Timer tool from the Designer software to check
the hold time for th is ma cro.
4. Delays based on 35 pF loading.
