Obtain & Install DSP Builder Accessing the DSP Builder Libraries from within MATLAB After installing DSP Builder, you can view DSP Builder libraries in the MATLAB software by performing the following steps: 1. Start the MATLAB software. (You can choose to automatically start MATLAB at the end of the install program.) 2. Click the Start icon in the lower left corner of the main MATLAB window. Point to Simulink and click Library Browser.

DSP Builder Release Notes Using Multiple Versions of MATLAB You specify the MATLAB installation that you want to use with DSP Builder during DSP Builder installation. If you have more than one MATLAB installation (for example, release R2006a and R2006b) you can register DSP Builder with another version using the following procedure: 1. Open a command prompt and change directory to the DSP Builder installation: cd dsp_builder 2.

Set Up Licensing ● ● The ModelSim simulator The Precision RTL synthesis software 2. Open the DSP Builder license file in a text editor. The file should contain one FEATURE line, spanning two lines. 3. Open your Quartus II license.dat file in a text editor. 4. Copy the FEATURE line from the DSP Builder license file and paste it into the Quartus II license file. 1 5. Do not delete any FEATURE lines from the Quartus II license file. Save the Quartus II license file.

Upgrading Your Existing Models 4. Enter the following command at the MATLAB prompt: alt_upgradeModel option1 option2 ... Any number of the available options can be used in any order. Table 2 describes the available options. Table 1. Options to the altUpgradeModel Command Option Description UnlockLibraries Causes libraries to be recursively unlocked and modified if referenced from the upgraded design. Already-unlocked libraries are always upgraded.

DSP Builder Release Notes Table 2 lists some of the issues which may require attention. Table 2. Model Upgrade Issues Issue Action PLL output clocks cannot be named In previous versions of DSP Builder, it was possible to have a PLL block and multiple ClockAltr blocks which represented PLL outputs. The PLL output clocks took the names of the clock blocks. This feature is not supported in v7.1 and cannot be automatically fixed. In v7.1, the PLL output clocks are named _clk.

Upgrading Your Existing Models Table 2. Model Upgrade Issues Issue Action The BP block does not support sample time mode A warning is issued if your design includes a Bus Probe (BP) block which was set to display the sample time because this option is no longer supported. Phase selection has been standardized across all blocks This may result in behavioral change when upgrading blocks that use phase selection.
