Hello, everyone. I'd like to ask

I now ask. JIC file, each in its structure has a CRC check, where can I find or provide a document

thank you

    Hi,


    Unfortunately we do not have the file to provide the information related to CRC checl.

      Hello,

      do you mean there is no CRC code similar to bin file in JIC? So, is it similar to the data that can prove the uniqueness of the JIC file?

      Hi

      Do you have this document, or know the name of this document, I will try to find it

    Hi,


    I make a mistake on mentioning JIC is user readable. Actually JIC is a binary file which is only readable by Quartus. We do not release any document or guide on how to check the file.

      hi，

      What about RPD ？

      thanks

    Hi,


    Same with RPD file where it is a binary file. We are not able to released how the format structure as it is confidential.

      Hello

      what else can identify JIC and read it as data

      thanks

    Hi,


    Unfortunately there is no way to read the file as it is a binary data.

      hi ，

      Thank you very much for your patience in answering the questions. I hope you can give me a suggestion now. Is there any way to identify the uniqueness of JIC files.

      hi

      I want the data that can prove the uniqueness of this JIC file, just like CRC validation code, can prove its uniqueness

      thanks

    Hi,


    Each generation of the JIC file will varies. Not sure if this uniqueness is sufficient?

      hi

      Because I want to pass the last generated JIC file to others through this unique "data", and then ensure that this JIC file is the last one I generated and transferred to him.This' data 'can be seen.

      thanks

    Hi,


    Unfortunately there is no way to determine the jic file as it is only binary file which is used to program into the flash.
