This feature can be used if user decided that they wish to lock 'N' address segments at their current addresses while moving the remainder of the segments to new addresses.

  1. You can lock the Block RAM using the Tcl command set_property locktype local [get_bd_addr_segs {versal_cips_0/FPD_CCI_NOC_0/SEG_axi_bram_ctrl_0_Mem0}]. Following is the CIPS_DDR_PL_debug example design, which locks the block RAM at their current addresses but assigns everything else.

    You can also lock the block RAM using the GUI as shown in the following figure.

  2. After the segment is locked, it is grayed out in the address editor as shown in the following image.

  3. Unassign all would unassign every master segment in the design, except for the segments locked, that is, CIPS- block RAM address segment.

  4. Locked segments cannot be unassigned individually, nor can their ranges or offsets be changed, while they are in the locked state.
  5. You then can call assign BD address to reassign all except the locked segment.
