1. In Qsys, create a new system called, memory_tester_system.

2. For the clk instance, turn off Clock frequency is known to indicate that the higher-level hierarchical

system that instantiates this subsystem provides the clock frequency.

3. In the IP Catalog, select the Avalon-MM Pipeline Bridge to add to your Qsys system.

4. For the Avalon-MM Pipeline Bridge, in the parameter editor, type 13 for the Address width.

To accommodate for the address translation from master to slave, that is a byte address as the input,

and a word address (4 bytes) as the output, the address width increases from 11.

5. Rename the instance to mm_bridge.

6. Set the mm_bridge_clk interface to clk_0.

7. Export the mm_bridge s0 interface with the name slave.

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.

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
