AR# 35289 MIG v3.4, Spartan-6 FPGA LPDDR - When running the LPDDR design the traffic generator stops sending commands after long write bursts

Description

For Spartan-6 FPGA LPDDR designs, the traffic generator used in the MIG example design may stop sending commands after long write bursts. This only affects the example design and not the user design.


Solution

This is due to a known issue in the traffic generator code and the use of the mcb_full signal. To correct this, the mcb_wr_full signal should be used instead.

This issue is resolved in the next release of the MIG controller 3.5, available with ISE Design Suite 12.2.
