ERROR: [BD 41-2666] NoC BDC Aperture Error: Dead-end Aperture - 2023.2 English

Issue: When running Generate Block Design in step 1, Vivado reports the following error message:

ERROR: [BD 41-2666] NoC BDC Aperture Error: Dead-end aperture. BDC Aperture 0x800000000 [0x180000000] on /VitisRegion/DDR_2 is not used by any downstream NoC endpoints or BDC boundary apertures. A NoC BDC aperture must have a path to a NoC endpoint or downstream BDC aperture that covers the upstream BDC aperture. Downstream endpoints: /noc_ddr/MC0_2

Solution:

The error message shows that the BDC Aperture 0x800000000 [0x180000000] on the BDC interface /VitisRegion/DDR_2 is not used by downstream NOC endpoint /noc_ddr/MC0_2. It is because the noc_ddr only enables 2 GB memory space. Check that you followed the noc_ddr setup instructions to enable DDR LOW 1 address region.
