6.1.2. FPGA Timing Analysis

When you generate the LVDS SERDES IP, the IP generates the SERDES hardware clock settings and the core clock for IP timing analysis.
Table 32.  Clocks for the Transmitter and Receiver in Non-DPA and DPA-FIFO ModesBecause the frequency of LVDS fast clock is higher than the user core clock by the serialization factor, the IP also creates multicycle path constraints for proper timing analysis at the SERDES–core interface.
