1.5.4.2. SERDES in LEs

For receiver designs that are using the SERDES in LEs, you must ensure proper timing constraints for the TimeQuest timing analyzer tool in the Intel® Quartus® Prime software to indicate whether the SERDES captures the data as expected or otherwise.

For dedicated SERDES and SERDES in LEs, you can set the timing constraints using the following methods:

  • Setting timing constraints using the TimeQuest Timing Analyzer GUI
  • Setting timing constraints manually in the .sdc.
