DDR3 Memory Port not be allocated

Jump to solution

Hello!

I have a design with DDR3 SDRAM, using MIG v4.1 successfully with Vivado 2018.1 version.  After upgrading to MIG v4.2 with 2018.3 version, I get the error shown below when I try to validate the pinout.

Hello @driss,

I was able to get development to "uprev" the patch in AR71898 to include a fix for your issue. I will send it to you directly through EZmove. I am working on getting the AR updated/pushed external again with the new documented issues/fixes.

https://www.xilinx.com/support/answers/71898.html - When pushed public again, will include AR71898_vivado_2018_3_preliminary_rev2.zip and no longer include AR71898_vivado_2018_3_preliminary_rev1.zip (as all of rev1 fixes are included in rev2.)

Please mark this post as a solution when you have verified your issue is resolved with the rev2 patch.

Thanks,
Cory

Hello @driss,

Do you run into this issue while using the patch provided in https://www.xilinx.com/support/answers/71898.html. We had some regressions in 2018.3 7-Series MIG that this patch should alleviate.

Thanks,
Cory
