Hi Bob, This is expected with the CG_400 because it does not have the DDC/DUC blocks due to the high resource requirements for handling 500 Msps. If you want 500 Msps, use CG_400. If you want 250 Msps or lower, use X4_200 (or another _200 variant). Take a look at the FPGA image flavors in the X410 manual for an overview.
