I have encrypted .pof file for Max 10 device with bitstream encryption.
I want to check if the version that I use is encrypted or not (because we have in our lab an encrypted and unencrypted versions).
Is there anyway to check if the version is encrypted? Maybe a register that can tell me that?
Sorry there is no such register. May i know have you enabled JTAG secure mode along with the tamper bit set? If so, probably you can try to detect the device with a USB Blaster and see if can detect or not.
Else, you will need to try to program unencrypted bitstream to figure out which device is encrypted.
