Adding Comments to Blocks
Adding Comments to Blocks
You can add comments to any DSP Builder block by right-clicking on the block to
display the Block Properties dialog box and entering text in the Description field of
the dialog box ( Figure 3–21 on page 3–24 ).
Figure 3–21. Adding Comments to a Block
DSP Builder includes the comment text next to the instantiation of the block in the
generated HDL.
Adding Quartus II Constraints
You can set Quartus II global project assignments in your Simulink model by adding
Quartus II Global Project Assignment blocks from the AltLab library. Each block
sets a single global assignment but you can use multiple blocks for multiple
assignments. You can use these assignments to set Quartus II compilation directives,
such as target device or timing requirements.
f For a description of the Quartus II Global Project Assignment block, refer to the
DSP Builder Reference Manual .
You can add additional Quartus II assignments or constraints that are not supported
in DSP Builder by creating a Tcl script in your design directory. Any file named < model
name >_add_user.tcl is automatically sourced when you run Signal Compiler .
The Tcl file can include any number of Quartus II assignments with the syntax:
