check if a MAX10 version is encrypted or not

Hi there.

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?

Regards,

Asaf

    Hi,


    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.


    Regards,

      I don't use tamper bit. I'm using an ekp file for encryption
