Why are different Bitstream Version values reported when the fpgainfo fme command is run on multiple identically configured Programmable Acceleration Cards with Arria® 10 GX?

Environment

  • Intel® Quartus® Prime Pro Edition
  • BUILT IN - ARTICLE INTRO SECOND COMPONENT
    Description

    Due to a problem with the fpgainfo tool in the Intel® Acceleration Stack Version 1.2, different Bitstream Version values are reported when the fpgainfo fme command is run on multiple Programmable Acceleration Cards with Arria® 10 GX which have the Intel® Acceleration Stack Version 1.2 installed on them.

    Some cards display a five-digit Bitstream Version (example: 0x30201) whereas others display a twelve-digit Bitstream Version (example: 0x564500030201).

    Resolution

    The Bitstream Version indicates an internal build number for the FPGA Interface Manager (FIM). To work around this problem in the Intel® Acceleration Stack Version 1.2, please refer to the lowest 5 digits in the bitstream version to ensure the same FIM has been loaded on all the cards, and ignore all higher digits. The recommended flow is to compare the PR Interface ID which is also reported by the fpgainfo fme command to determine that the cards have all been configured with the same FIM, instead of referring to the Bitstream Version.

    This problem is currently scheduled to be resolved in a future release of the Intel® Acceleration Stack.
