Follow these steps to change the Burst Type value.

  1. Generate DDR4 PHY_ONLY IP.
  2. In the Generate Output Products option, do not select Generate instead select Skip.
  3. Set the Burst Type value by running the following command on the Tcl console:
    set_property -dict [list CONFIG.C0.DDR4_BurstType <value_to_be_set>] [get_ips <ip_name>]

    For example:

    set_property -dict [list CONFIG.C0.DDR4_BurstType {Interleaved}] [get_ips <ddr4_0>]
  4. Generate output files by selecting Generate Output Products after right-clicking IP.

The generated output files have the Burst Type value set as per the selected value.
