Running generate bitstream resulted in an error message. Have you seen this?

[DRC INBB-3] Black Box Instances: Cell 'mac/DSP48A1_inst' of type 'DSP48A1' has undefined contents and is considered a black box. The contents of this cell must be defined for opt_design to complete successfully.

Had the same issue on 2023.1. I removed the dsp.v source and got past this, seems it wasn't used in the final block design. Also ran into an issue with the test_nes source, seems that the nes_dp module inputs would need fixing to allow the test to run, not used in final design if you just want to generate the bitstream for it.
