UDIMM Support on U200

Jump to solution

Hi all,

We use Vivado to develop designs that implement a DDR4 MIG for Alveo U200 boards. These designs use the constraints provided in the xtp572-alveo-u200-xdc file. Our designs work fine when we use DDR4 RDIMMs.

We see that the Alveo U200 board supports DDR4 UDIMMs in an old version of the Alveo U200 and U250 Accelerator Cards User Guide (UG1289 (v1.1.1) November 20, 2019). We tried getting our designs to work with UDIMMs by modifying the MIG IP and the constraints provided by Xilinx but we failed. We could not find any constraints targeting UDIMM devices for the U200 board.

Is it possible for the U200 to work with UDIMMs? Are we doing something wrong? Can you provide us with the constraints targeting DDR4 UDIMM designs if there is any?

Thanks

An update on this:

We were able to get x8 dual rank UDIMMs working on our Alveo U200 boards using the constraints in the attached txt file. These constraints target channel C1 on the board for DDR4 PHY.
