Creating a Library Model File
Building the HDL Subsystem Functionality
DSP Builder Standard Blockset User Guide
To create a Library Model File for your custom block, follow these steps:
1. In MATLAB, change the current directory setting to: <DSP Builder install
2. Open the Simulink Library Browser. On the File menu in the Simulink Library
3. Expand the Simulink Ports & Subsystems library in the Simulink Library Browser
4. Click on the Subsystem text below the block and rename the block DelayFIFO.
5. Click Save on the File menu and save the library file as NewLib.mdl.
To add functionality to the DelayFIFO block, follow these steps:
1. Double-click on the DelayFIFO block to open the NewLib/DelayFIFO subsystem
2. Drag and drop a Shift Taps block from the Storage library in the Altera DSP
