  2. Select Pattern Selection from the drop-down list—Increment, Decrement, Fill with Zeros, Fill with Ones, Fill with all A’s and Fill with all 5’s. For successful Memory test operation, the Pattern Type for Mem Init and Pattern Type for Mem Test should be same.
  3. Click Memory Test.
    • GUI sends command to fabric logic to initiate the LSRAM/DDR3L/DDR4 memory
    • GUI sends command to fabric logic to read and compare LSRAM/DDR3L/DDR4 memory

    The following figure shows the UART—Memory Test tab.
