How to constrain VDMA IP to make it uses all BRAMs instead of URAM

Jump to solution

I am using VDMA IP with XCZU11EG device and it automatically uses URAM, and in my design the amount of URAM is not so enough and I want the VDMA to use only BRAM.

How to constrain or configure VDMA IP to make it uses all BRAMs instead of URAM?

HI @bhwxl123 

I do not think this is controlled by the AXI VDMA IP. You can try applying vivado synthesis settings to limit the number of URAMs. Refer to UG901

Thank you very much for replying. I will try the synthesis settings or to optimize my whole project.
