Implementing an SMBus Controller (AN 502)  

CategoryDesign Example
NameImplementing an SMBus Controller (AN 502)
DescriptionSMBus, a derivative of I2C, is a two-wire interface through which various system components can communicate with each other and with the rest of the system. At any time, only one device can master the bus to conduct transactions with one slave or with multiple slaves.

You can use an SMBus as a control bus for system and power management related tasks. You can remove individual control lines because an SMBus can be used to communicate with multiple devices. This not only reduces pin count, but also ensures future expansion.

The designed controller follows SMBus specifications, version 2.0 (see

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>/AN502_MAX10.par

Once the process completes, then type:

quartus_sh --platform –name AN502_MAX10
