Voltage Level Shifters (AN 490)  

CategoryDesign Example
NameVoltage Level Shifters (AN 490)
DescriptionDevices on one circuit board can potentially use many different supply voltages, such as 5V, 3.3V, 2.5V, 1.8V and 1.5V. Therefore, the buses connected to a system can have different voltage standards that can lead to voltage-level conflicts. MAX 10 FPGAs are designed to interface directly with 1.5-V, 1.8-V, 2.5-V, and 3.3-V signals and can be used to eliminate these conflicts.

MAX 10 FPGAs can interface with other devices using different voltage levels because the core power supply voltage (VCCINT) is separate from the FPGA output voltage (VCCIO). A few applications for voltage level shifting are:
• Interfacing microprocessors with peripheral devices, timers, and transceivers that are operating at different I/O standards and levels
• Driving more than one set of GPIO pins having different I/O standards

Installation Package

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>/AN490_MAX10.par

Once the process completes, then type:

quartus_sh --platform –name AN490_MAX10
