1.5.1.2. Add the Pattern Checker

The pattern checker system validates data that arrives via an Avalon-ST sink interface. You control the system by accessing the memory locations allocated to each component within the subsystem. The system connects all of the slave ports to a pipeline bridge, which it then exposes outside of the system.

The pattern checker system contains the following components:

  • Pipeline bridge
  • Custom pattern checker
  • PRBS pattern checker
  • One-to-two demultiplexer
  1. In the IP Catalog, double-click pattern_checker_system from the System group.
  2. In the parameter editor, click Finish to accept the default settings.
  3. Rename the instance to pattern_checker_subsystem.
  4. Set the pattern_checker_subsystem clk to clk_0.
  5. Connect the pattern_checker_subsystem slave interface to the mm_bridge m0 interface.
  6. Connect the pattern_checker_subsystem reset interface to the clk_0 clk_reset interface.
