Page 22 Using the PFL Megafunction Instantiating the PFL Megafunction To instantiate the PFL megafunction, follow these steps: 1. In the Quartus II software, on the Tools menu, click MegaWizard Plug-In Manager. 2. Select Create a new custom megafunction variation and click Next. 3. For Which device family will you be using, select the MAX II device. If you are using a MAX V device, select the MAX V device. 1 You can also instantiate the PFL megafunction in other FPGA device families. 4. Under JTAG-accessible Extensions, select Parallel Flash Loader. 5. Select the Hardware Description Language (HDL) output file type. For this example, select Verilog HDL. 6. Click Next. 7. Specify the directory and output filename. 1 Altera recommends instantiating the megafunction in your CPLD top-level design. 8. Click Next to display the Parameter Settings page. 9. Specify the parameter settings. 1 For more information about the parameters and the allowed values, refer to Table 13 on page 38. 10. Click Next or click the EDA tab to display the EDA page. The EDA page shows that the PFL megafunction cannot perform simulation because there are no simulation files. 1 The Quartus II software does not support the JTAG pins simulation or the Altera CPLD or flash memory device programming. However, simulation is possible for FPGA configuration, on the condition that your FPGA has the proper flash vectors and FPGA responses. Examples of flash vectors are flash_addr and flash_data; examples of FPGA responses are fpga_conf_done and fpga_nstatus. f For more information about the signals, refer to Table 14 on page 43. 11. Click Next or click the Summary tab to display the Summary page. 12. Select any additional file types that you want to create and click Finish. The Quartus II software generates the PFL megafunction files you select. 1 By default, all unused pins are tied to ground. Altera recommends setting all unused pins to tri-state because doing otherwise might cause interference. To set all unused pins to tri-state, in the Quartus II software, click Assignments>Device>Device and Pin Options>Unused Pins and select an item from the Reserve all unused pins list.

Using the PFL Megafunction Page 23 Converting .sof Files to a .pof To generate a programming file with different compression features, you must convert the .sof files to a .pof. To convert the .sof files to a .pof, follow these steps: 1. On the File menu, click Convert Programming Files. 2. For Programming file type, specify Programmer Object File (.pof) and name the file. 3. For Configuration device, select the CFI or NAND flash memory device with the correct density. For example, CFI_32Mb is a CFI device with 32-Megabit (Mb) capacity. 4. To add the configuration data, under Input files to convert, select SOF Data. 5. Click Add File and browse to the .sof files you want to add. You can place more than one .sof in the same page if you intend to configure a chain of FPGAs. The order of the .sof files must follow the order of the devices in the chain. If you want to store the data from other .sof files in a different page, click Add SOF page. Add the .sof files to the new page. 6. Select SOF Data and click Properties to set the page number and name. Under Address mode for selected pages, select Auto to let the Quartus II software automatically set the start address for that page. Select Block to specify the start and end addresses, or select Start to specify the start address only. 7. Click OK. 8. You can also store Hexadecimal (Intel-Format) File (.hex) user data in the flash memory device: a. In the Input files to convert sub-window of the Convert Programming Files window, select Add Hex Data. b. In the Add Hex Data dialog box, select either absolute or relative addressing mode. ■ ■ If you select absolute addressing mode, the data in the .hex is programmed in the flash memory device at the exact same address location listed in the .hex. If you select relative addressing mode, specify a start address. The data in the .hex is programmed into the flash memory device with the specific start address, and the differences between the addresses are kept. If no address is specified, the Quartus II software selects an address. 1 You can also add other non-configuration data to the .pof by selecting the .hex that contains your data when creating the flash memory device .pof. 9. Click Options to specify the start address to store the option bits. This start address must be identical to the address you specify when creating the PFL megafunction. Ensure that the option bits sector does not overlap with the configuration data pages and that the start address resides on an 8-KB boundary.
