The dataflow netlist is a subset of your original design netlist. When you generate the dataflow netlist, Vivado trims out the following:

  • Scalar nets
  • Bus nets below the -min_bus_width threshold (default:16)
  • Registers
  • LUTs that do not significantly influence the datapath

The dataflow netlist includes the following:

  • Bus nets equal to or above the -min_bus_width threshold
  • Significant cells that impact placement include the following items:
    • BlockRAMs
    • UltraRAMs
    • LUTRAMs
    • DSP slices
    • Hard IP
    • Gigabit transceivers
    • NoC
  • Hierarchical cells
  • Clock nets
