In this example, some data from the files Sample1, Sample2 and Sample3 are written
to one chip. The data from the address 200 (Hex) of the file Sample1 will be written
to the address 0 of the chip. The data from the address 0 (Hex) of the file Sample2
will be written to the address 3000 (Hex) of the chip. The data from the address 4000
(Hex) of the file Sample3 will be written to the address 4000 (Hex) of the chip.
Step one: Open 'Buffer Edit' dialogue box, leave the option 'Clear Buffer During File
Loading' unselected.
Step two: Click "Load file", Select file Sample1. In the "File Type" dialog box, enter
0 in the buffer start address line and 200 in the file start address line. Load the file
"Sample1". Select the file Sample2. Enter 3000 in the buffer start address line and 0
in the file start address line. Load the file "Sample2". Then select the file Sample3.
Enter 4000 in the buffer start address line and 4000 in the file start address line. Load
the file 'Sample3'.
Step three: Program files
The user can also save the data in buffer to a file Sample4, then directly load Sample4
and program next time if there is no change about requirement of this file and content
of the three files.
5.1.4 File of POF Format
When the PLD devices made by ALTERA are programmed, the data are saved in the
files of the POF format. When a file is loaded, a 'File Type' box will pop up to
prompt the user to select.
1) The POF file, which is created by a compiler, will be transformed into the Fuse
data and be checked when loaded to buffer.
Unmatched file to this chip: this means this POF file does not match this chip.
The POF file is related to the device when it is compiled. The error indicates that
this POF file is not for this device. Please replace it with a matched one.
The POF file has errors:
Load POF file dll error (not found): An auxiliary file has errors; please contact
technical support.
2) Files of other formats are mainly the JED files. The data in the buffer will be
directly saved in a JED file after the chip is read. This mode can be used when the file
is loaded next time.
5.2 Adapter Selection
The programmer has a standard configuration. It supports the DIP devices with 48 or
less pins. If the user wants his programmer to support the device which is non-DIP or
has more than 48 pins, an adapter is needed to convert the pins. There are two types
of adapters, universal and specific. Universal adapters are applicable for all devices of
same encapsulation and the same number of pins. Specific adapters are applicable for
