(Ask a Question)

Possible Reason
  Marginal issues on CA, Write DQ/DQS, or Read DQ/DQS. When the Sanity Check fails, a dialog box appears as shown in the following figure.
  Figure 5-19.Sanity Check

Workaround
  Configure any one of the following parameters to a different value using the MSS Configurator when the Sanity Check fails:
  - FPGA DQ Drive
  - FPGA DQS Drive
  - FPGA DQ ODT
  - FPGA DQS ODT
  - Memory Output Drive Strength
  The following figure shows the configuration of the DQ/DQS drive or ODT in the DDR Controller tab.
