Design Security Features (Encryption) - Indication for existing non-volatile key in the FPGA

Hey,

Is there an indication in Quartus for existing non-volatile key in the FPGA?

1. I programmed epk file, without 'Tamper protection bit', into the FPGA.

2. After I programmed the encrypted JIC file into the flash memory device and powered on, the FPGA didn't work.

3. when I programmed the normal JIC file into the flash memory device and powered on, It worked fine.

In all the above operations, the 'Programmer' tool reported that the programming process was successful.

I'm trying to figure out if programming the epk file was successful, because the 'Programmer' tool let me program the epk file into the FPGA over and over again, and I know that programming process should be one-time.

More details:

- FPGA - Cyclone V - 5CEFA7U19I7N.

- Configuration Scheme - AS QSPI (x4).

- Flash memory device - MT25QL256, Micron.

      Hey Aiman,

      I read this document and I didn't find the specific indication I needed.

      I just want an indication in Quartus for existing non-volatile key in the FPGA via JTAG communication.

      Thanks

    Hi,

    What do you mean by " indication in Quartus for existing non-volatile key in the FPGA via JTAG communication" ?

    All information for design security including non volatile are in the AN 556. Did you follow the steps in the AN 556?

    Regards,

    Aiman

      Hi Ayman,

      Yes, I followed the steps in the AN 556 document.


      This means that I am looking for an indication in Quartus or the other tools (Programmer and more..) via JTAG communication.

      The indication - is there a non-volatile key on this particular FPGA? - Yes or No.


      Thanks.
