Using the PFL Megafunction
The Quartus II Programmer allows you to program, verify, erase, blank-check, or
examine the configuration data page, the user data page, and the option bits sector
separately, provided the CPLD contains the PFL megafunction.
1 The Quartus II programmer erases the flash memory device if you select the .pof of
the flash memory device before programming. To prevent the Quartus II Programmer
from erasing other sectors in the flash memory device, select only the pages, .hex data,
and option bits.
If you intend to use the flash memory device to store user data only, hold the
pfl_nreset pin low at all times to prevent FPGA configuration.
To program the CPLD and the flash memory devices separately, follow these steps:
1. Open the Quartus II Programmer window.
2. Click Add File. The Add Programming File Window dialog box appears.
3. Add the targeted .pof, and click OK.
4. Check the boxes under the Program/Configure column of the .pof.
5. Click Start to program the CPLD.
6. After the programming progress bar reaches 100%, click Auto Detect. For
example, if you are using dual P30 or P33, the programmer window shows a dual
P30 or P33 chain in your setup.
Alternatively, you can add the flash memory device to the programmer manually.
Right-click the CPLD .pof and click Select Flash Device. In the Select Flash
Device dialog box, select the device of your choice.
7. Right-click the necessary flash memory device density and click Change File.
1 You must select the density that is equivalent to the sum of the density of
two CFI or NAND flash memory devices. For example, if you require two
512-Mb CFI flash memory devices, then select CFI 1 Gbit. For more than
one quad SPI flash memory device, select the density that is equivalent to
the sum of all the density of the quad SPI flash memory devices. For
example, a four quad SPI flash memory devices (128 Mb for each device),
the total density is equivalent to 512 Mb. A .pof with 512-Mb flash density
is required to program these quad SPI flash devices. The PFL megafunction
handles the 512-Mb .pof programming to the four quad SPI flash memory
devices.
8. Select the .pof generated for the flash memory device. The .pof for the flash
memory device is attached to the .pof of the CPLD.
9. Check the boxes under the Program/Configure column for the added .pof and
click Start to program the flash memory devices.
