LogiCORE Digital Pre-Distortion (DPD) v7.1 rev2 - changing Filter Memory Depth can cause the DPD core run to abnormally


Launch the Digital Pre-Distortion (DPD) IP GUI from the Vivado repository. Once the DPD IP GUI is visible click on Filter Memory Depth. The available range is 1, 2, 4, 5, 6.

This range is incorrect. The correct range is 1, 2, 4. If I select a filter memory depth of 5 or 6, it can result in unpredictable behavior and Vivado can hang.


The DPD GUI is showing an incorrect range. This is a known issue and has been fixed in the DPD v7.1 rev3 core.

This can be downloaded from the DPD evaluation lounge.
