Add the PRBS Pattern Checker

The PRBS pattern checker performs the opposite operation of the PRBS pattern generator. The processor

uses the memory-mapped csr slave interface to control the component. The st_pattern_input streaming

input accepts data from the one-to-two streaming demultiplexer.

1. In the IP Catalog, expand Memory Test Microcores, and then double-click PRBS Pattern Checker.

2. In the parameter editor, accept the default parameters, and then click Finish.

3. Rename the instance to prbs_pattern_checker.

4. Set the prbs_pattern_checker clock to clk_0.

5. Connect the prbs_pattern_checker csr interface to the mm_bridge m0 interface.

6. Assign the prbs_pattern_checker csr interface to a base address of 0x0440.

Add a One-to-Two Streaming Demultiplexer

The one-to-two streaming demultiplexer performs the opposite operation of the two-to-one streaming

multiplexer. It has a streaming input interface, st_input, that accepts data from the pattern reader, and

two streaming output interfaces, st_output_A and st_output_B, that connect to the custom pattern

generator and PRBS pattern generator. To allow the processor to program the data route through the

component, the system includes the slave interface, csr.

1. In the IP Catalog, expand Memory Test Microcores, and then double-click One-to-two Streaming

Demux.

2. In the parameter editor, accept the default parameters, and then click Finish.

3. Rename the instance to one_to_two_st_demux.

4. Set the one_to_two_st_demux clock to clk_0.

5. Export the one_to_two_st_demux st_input interface with the name st_data_in.

6. Connect the one_to_two_st_demux csr interface to the mm_bridge m0 interface.

7. Assign the one_to_two_st_demux csr interface to a base address of 0x0400.

8. Connect the custom_pattern_checker st_pattern_input interface to the one_to_two_st_demux

st_output_A interface.

9. Connect the prbs_pattern_checker st_pattern_input interface to the one_to_two_st_demux

st_output_B interface.

Verify the Memory Address Map

On the Address Map tab, verify that the entries in the Address Map table match the values in

#mwh1411073373020/table_54ED964DACCD4D7480A621FF0B0D0E00. Red exclamation marks

indicate that the address ranges overlap. Correct the base addresses, as appropriate, to ensure there are no

overlapping addresses, and your map matches this tutorial’s guidelines.
