(Ask a Question)

Possible Reason
  Signal integrity issues on CA or DQS lines. When the Read Gate training fails, a dialog box appears as shown in the following figure.
  Figure 5-5.Read Gate Training Fail

Workaround
  Configure any one of the following parameters to a different value using the MSS Configurator when the Read Gate training fails:
  - Memory Output Drive Strength
  - FPGA DQS ODT
  The following figure shows the configuration of output drive strength in the DDR Memory Initialization tab.
  Figure 5-6.Configuring Output Drive Strength—DDR Memory Initialization Tab
  The following figure shows the configuration of DQS ODT in the DDR Controller tab.
