Figure 12–9. The Quartus II Programmer Window with the Specific IPS File
Saving the IPS File Information to the Programming File
The pin state information in the IPS file can be saved into the POF to avoid requiring
two files. You will only need the programming file to program a device in ISP clamp
mode. This programming file is also used for creating the Jam and JBC files for the ISP
clamp so that the Jam or JBC files will contain the pin state information. The following
are the steps to save the pin state information from the IPS file to the programming
files.
1. Add in the programming file in the programmer window.
2. Add in the IPS file to the programmer.
3. Click Save File in the programmer window or on the Edit menu, and the Save
Data To File As dialog box will appear. See Figure 12–10.
4. Enter the file name, check the Include IPS file information box, and click Save.
The POF with saved IPS information only supports ISP clamp operation in the
Quartus II software and not with third-party programming tools. For third-party
tools, Jam or JBC files should be used if ISP clamp is required.
Figure 12–10. Save Data To File as Menu
When programming a device with the ISP Clamp box checked, the Quartus II
Programmer will first look for the IPS file. If the IPS file is not found, only then it will
look into the POF for the pin state information.
