Using the Internal Oscillator in MAX devices (AN 496)  

CategoryDesign Example
NameUsing the Internal Oscillator in MAX devices (AN 496)
DescriptionMost designs require a clock for normal operation. With an internal oscillator, MAX 10 devices do not require external clocking circuitry. For example, you can use the internal oscillator to meet the clocking requirement of an LCD controller, system management bus (SMBus) controller, or any other interfacing protocol, or to implement a pulse width modulator. This helps minimize component count, board space, and reduces the total cost of the system.

You can instantiate the internal oscillator without instantiating the UFM by using the MAX 10 oscillator megafunction in the Quartus® II software. The oscillator’s output frequency, OSC, is one-fourth of the undivided frequency of the internal oscillator.

Note: After downloading the design example, you must prepare the design template. The file you downloaded is of the form of a <project>.par file which contains a compressed version of your design files (similar to a .qar file) and metadata describing the project. The combination of this information is what constitutes a <project>.par file. In releases 16.0 or newer, you can simply double click on the <project>.par file and Quartus will launch that project.

The second means to bring up the project template is through the New Project Wizard (File -> New Project Wizard). After entering the project name and folder on the first panel, the second panel will ask you to specify an empty project or project template. Select project template. You will see a list of Design Templates projects that you have loaded prior as well as various "Baseline Pinout Designs" that contain the pinout and settings for a variety of development kits. If you don't see your design template in the list, click on the link that states install the Design Templates circled below:


Browse to the <project>.par file you downloaded, click next, followed by Finish, and your design template will be installed and displayed in the Project Navigator pane in Quartus.

Note: When a design is stored in the Design Store as a design template, it has been previously regression tested against the stated version of Quartus software. The regression ensures the design template passes analysis/synthesis/fitting/assembly steps in the Quartus design flow.

At the command-line, type the following command:

quartus_sh --platform_install –package <project directory>/AN496_MAX10.par

Once the process completes, then type:

quartus_sh --platform –name AN496_MAX10
