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.
