1.5.1.3.2. Add a Pattern Reader Component

The pattern reader component accepts memory transfer commands from the RAM test controller with the command streaming interface. The mm_data interface reads the pattern data from the SDRAM controller. The st_data interface sends the data read from memory to the design’s pattern checker.
  1. In the IP Catalog, double-click Pattern Reader from the Memory Test Microcores group.
  2. n the parameter editor, turn on Burst Enable.
  3. Ensure the Maximum Burst Count is 2.
  4. Ensure that Enable Burst Re-alignment is turned on.
  5. To accept the other default parameters, click Finish.
  6. Rename the instance to pattern_reader.
  7. Set the pattern_reader clock to clk_0.
  8. Connect the pattern_reader st_data interface to the pattern_checker_subsystem st_data_in interface.
  9. Export the pattern_reader mm_data interface with the name read_master.
