Hi Jay,
These are the steps to set the secure JTAG settings on your device:
1. On the File menu, click Convert Programming Files.
2. Under Output programming file, select Programmer Object File (.pof) in the Programming file type list.
3. In the Mode list, select Internal Configuration .
4. To set the ICB settings, click
option/boot info and the
icb setting dialog box will appear.
5. Select the
jtag secure option.
6. Verify Protect.
7. Allow encrypted POF only
8. After all settings are set, click Generate to generate related programming file.
the jtag secure feature will be disabled by default in intel quartus prime. if you are interested in using the jtag secure feature, contact intel for support.
max 10 fpga device would become permanently locked if you enabled jtag secure mode in the pof file and pof is encrypted with the wrong key. you must instantiate the internal jtag interface for you unlock the external jtag when the device is in jtag secure
mode.
