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

Description

Version Found: v5.0
Version Resolved: See (Xilinx Answer 58435)
 
AXI narrow bursts will cause warnings in the MIG Example Design simulation.

A warning similar to below 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 when:

1. The PHY ratio is 4:1.

2. MC = X.

3. AXI data width is less than (X*8)

Solution

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