UltraScale DDR4 - AXI Narrow Burst simulations cause model warnings to be generated

描述

Version Found: DDR4 v5.0

Version Resolved: See (Xilinx Answer 69035)

AXI narrow bursts will cause warnings in the MIG Example Design simulation.

A warning similar to the following will be shown:

Model:WARNING: Reading unwritten address: C:0 BG:0 B:1 R:5b6d C:28e dm:0 @81032659
An error in the Traffic Generator may occur in HW as the Traffic Generator does not support narrow bursts at this time.

 

This will occur under the following conditions:

  1. The PHY ratio is 4:1.
  2. MC = X.
  3. AXI data width is less than (X*8)

解决方案

To work around this issue, you will need to turn off the narrow burst option in the GUI until this issue has been resolved.
