4.5.6.2.1. <variation_name>.sdc

You can find the location of the <variation_name> .sdc file in the .qip or .qsys, which is generated during the IP generation. The <variation_name> .sdc allows the Fitter to optimize timing margins with timing driven compilation and allows the Timing Analyzer to analyze the timing of your design.

The IP uses <variation_name> .sdc for the following operations:

  • Creating clocks on PLL inputs
  • Creating generated clocks
  • Calling derive_clock_uncertainty
  • Creating set_output_delay and set_input_delay constraints to analyze the timing of the read and write paths
