1.5.1.1. Add the Pattern Generator

The custom pattern generator system provides a stream of pattern data via an Avalon-ST source interface. You control the system by accessing the memory locations allocated to each component within the subsystem. The system connects slave ports to a pipeline bridge, which it then exposes outside of the system.

The pattern generator system contains the following components:

  • Pipeline bridge
  • Custom pattern generator
  • PRBS pattern generator
  • Two-to-one streaming multiplexer
  • Streaming timing adapters
  1. In the IP Catalog, under Project expand System, and then double-click pattern_generator_system.
  2. In the parameter editor, click Finish to accept the default settings.
  3. Rename the instance to pattern_generator_subsystem.
  4. Set the pattern_generator_subsystem clk to clk_0.
  5. Connect the pattern_generator_subsystem slave interface to the mm_bridge m0 interface.
  6. Connect the pattern_generator_subsystem reset interface to the clk_0 clk_reset interface.
