Chapter 7: Using the Interfaces Library
Avalon-MM Interface Blocks Design Example
You can re-size a block by dragging the resize handles at each corner.
Figure 7–7. topavalon.mdl Design Example
11. Drag and drop another Avalon-MM Slave block into the top right of your model
and change the name of this block instance to Avalon_MM_Read_Slave.
12. Double-click on the Avalon_MM_Read_Slave block to bring up the Block
Parameters dialog box.
13. Select Read for the address type, Signed Integer for the data type, and specify 8
bits for the data width.
14. Click OK and notice that the Avalon_MM_Read_Slave block redraws with three
ports: Address i1:0 , Read ibit , and Read Data o7:0 .
15. Complete your design by connecting the Avalon_MM_Read_Slave ports
( Figure 7–7 ).
f The default design example uses the Stratix III Development Board. If you
have a different board (such as the Cyclone III Development Board), you
must replace the board block and analog-to-digital converter blocks by
corresponding blocks for the appropriate board. For more information,
refer to the Boards Library chapter in the DSP Builder Standard Blockset
Libraries section in volume 2 of the DSP Builder Handbook .
16. Add oscilloscope probes to monitor the signals on the DSP development board.
17. Click Save on the File menu in your model window to save your model.
