Page 30 Using the PFL Megafunction 1 Before you perform the device configuration simulation, ensure that the PFL megafunction receives the correct option bits address and associated values to guarantee correct simulation output. Figure 18. Simulation Before Configuration After reading the option bits for page 0, the PFL megafunction waits for a period of time before the configuration starts. The flash_data remains at 0×ZZ within this period. Configuration starts when the fpga_dclk starts to toggle. During configuration, the PFL megafunction asserts the flash_nce and flash_noe signals low, and the pfl_flash_access_request signal high.

Using the PFL Megafunction Page 31 Figure 19 shows the simulation when the FPGA configuration starts. Figure 19. Simulation When FPGA Configuration Starts The FPGA configuration continues until the fpga_conf_done signal is asserted high, which indicates the configuration is complete. After the configuration process completes, the PFL megafunction pulls the flash_nce and flash_noe signals high and the pfl_flash_access_request signal low to indicate the configuration data is no longer being read from the flash memory device. Programming Altera CPLDs and Flash Memory Devices Using the Quartus II Programmer, you can program Altera CPLDs and flash memory device in a single step or separate steps. To program both in a single step, first program the CPLD, then the flash memory device. Follow these steps: 1. Open the Quartus II Programmer window and click Add File to add the .pof for the CPLD. 2. Right-click the CPLD .pof and click Attach Flash Device. 3. In the Flash Device menu, select the density of the flash memory device to be programmed. 4. Right-click the necessary flash memory device density and click Change File. 5. Select the .pof generated for the flash memory device. The .pof for the flash memory device is attached to the .pof of the CPLD. 6. Add other programming files if your chain has other devices. 7. Check all the boxes in the Program/Configure column for the new .pof and click Start to program the CPLD and flash memory device.
