CompactFlash+ Interface (AN 492)  

CategoryDesign Example
NameCompactFlash+ Interface (AN 492)
DescriptionCompactFlash cards are used to store and transport several forms of digital information (data, audio, pictures) and software between a wide span of digital systems. The CompactFlash association introduced the CF+ concept to enhance the operation of CompactFlash cards with I/O devices and magnetic disk data storage apart from flash memory. The CF+ card is a small form factor card that includes compact flash storage cards, magnetic disk cards, and various I/O cards that are available in the market, such as serial cards, ethernet cards, and wireless cards. The CF+ card includes an embedded controller that manages data storage, retrieval and error correction, power management, and clock control. CF+ cards can be used with passive adapters in PC-Card type-II or type-III sockets.

Nowadays, many consumer products such as cameras, PDAs, printers, and laptops have a socket that accepts CompactFlash and CF+ memory cards. In addition to storage devices, this socket can also be used to interface I/O devices that use the CF+ interface.

This design example uses a CF+ device, which functions in two modes: PC Card ATA using I/O mode and PC Card ATA using memory mode. The third optional mode, True IDE mode, is not considered. The MAX 10 FPGA operates as the host controller and acts as a bridge between the host and the CF+ card.

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>/AN492_MAX10.par

Once the process completes, then type:

quartus_sh --platform –name AN492_MAX10
