UltraZed-EV SOM memory

Question

I'm migrating from the PicoZed SOM to the UltraZed-EV SOM.

In Vivado, I'm trying to configure the DDR for the Zynq UltraScale+ MPSoC. According to the "UltraZed-EV SOM Hardware User Guide" (LIT# UG-AES-ZU7EV-SOM-G-V1.2), the memory is: MT40A512M16JY-083E IT:B. There is no preset for this part in Vivado. After some quick research, it appears this part is obsolete. If this is true, I'm hesitant to continuing to use this SOM. My project must last for years in the future. Can anyone confirm this is the part used on the SOM and whether it is obsolete?

Also, if this is correct, can anyone share the settings for Vivado for this part?

Thanks.

UltraZed-EV has a long life ahead of it, likely 7+ years. I know the team was qualifying a new memory. I can find out and get back with you. However, we will continue to operate the Avnet designs using the settings from the original memory since that is how the board was validated. The new Micron memory is backwards compatible with the old one. For the settings, you should be using the Avnet board definition, which you can get from the Avnet github or the Xilinx BoardStore inside Vivado. I can give you more guidance on that if you need it.

If you are downloading from Avnet GitHub, then take a look at this blog How to Leverage Board Presets to Accelerate Your Vivado Design If you want to use the Xilinx BoardStore, then read here Xilinx BoardStore to Automate Vivado Board Definitions for Avnet Boards I looked at the latest Bill of Materials for UltraZed-EV, and the memory currently being used is Micron MT40A512M16LY-062E IT:E. Not only is it in Production, but as part of Micron's Product Longevity Program, it will be around for at least 10 years from the start date in 2020. https://www.micron.com/products/dram/ddr4-sdram/part-catalog/mt40a512m16ly-062e-it Bryan
