5.8.3. High-Speed I/O Timing Budget

The LVDS I/O standard enables high-speed transmission of data. To take advantage of the fast performance, analyze the timing of high-speed signals. The basis of the source synchronous timing analysis is the skew between the data and the clock signals instead of the clock-to-output setup times. Use the timing parameters provided by IC vendors. High-speed differential data transmission is strongly influenced by board skew, cable skew, and clock jitter.

Intel® Cyclone® 10 LP devices implement the SERDES in LEs. You must set proper timing constraints to indicate whether the SERDES captures the data as expected or otherwise. You can set the timing constraints using the Timing Analyzer tool in the Intel® Quartus® Prime software or manually in the Synopsys* Design Constraints (.sdc) file.
