In case of name conflict between two auto-generated clocks, the Vivado IDE adds unique suffixes to differentiate them, such as:

  • usrclk
  • usrclk_1
  • usrclk_2

To force the name of the generated clocks:

  • Choose unique and relevant net names in the RTL, or
  • Use create_generated_clock to force the name of the generated clocks.
