To use FIR Compiler to create a MegaCore function variation that fits the specific
needs of your design, follow these steps:
1. Double-click the my_fir_compiler block to start IP Toolbench.
2. Click Step 1: Parameterize to specify how the FIR filter should operate.
3. Use the default values, specifying a low-pass filter. Click Finish.
After you parameterize the MegaCore function, to generate the files for inclusion in
the Simulink model and simulation, follow these steps:
1. Click Step 2: Generate in IP Toolbench.
2. The generation report lists the design files that IP Toolbench creates.
3. Click Exit.
For more information about the FIR Compiler including a complete description of the
generated files, refer to the
The my_fir_compiler block in the Simulink model updates to show the input and
output ports for your configuration
connect it to the rest of your Simulink design.
