3. Click OK .
4. On the Simulation menu in the simulink model, click Start . The scope output
shows the effect of the low-pass filter in the bottom window ( Figure 4–6 ).
Figure 4–6. Simulation Output
Check that the FIR filter block behaves as you expect and filters high-frequency
data as a low-pass filter.

You may need to use the Autoscale command in the Scope display to view
the complete waveforms.
Compiling the Design
To create and compile a Quartus II project for your DSP Builder design, and to
program your design onto an Altera FPGA, add a Signal Compiler block. Follow
these steps:
1. Select the AltLab library from the Altera DSP Builder Blockset folder in the
Simulink Library Browser.
2. Drag and drop a Signal Compiler block into your model.
