Does the Intel® Stratix® 10 FPGA firmware apply optimized on-chip voltage regulator trim settings in designs using the Intel® Quartus® Prime Pro Edition Software versions 18.0 update 1 and later?

Environment

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

    Critical Issue

    Description

    Intel has determined that Intel® Stratix® 10 FPGA firmware is not applying optimized on-chip voltage regulator trim settings and therefore may cause a slight timing model mis-correlation.

    Resolution

    The optimized settings are available through an updated Intel® Stratix® 10 FPGA firmware with optimized on-chip voltage regulator trim settings that restore the timing model correlation. Intel requires that customers apply the updated firmware to future Intel® Stratix® 10 devices (see table below).

    This firmware update:

    • Does not require recompilation or change design timing
    • Has no impact on design functionality or performance
    • Has no impact on power specifications as power models in EPE are already based on optimized regulator trim settings
    • Has no impact to form, fit, or function

    Refer to the following table to determine the appropriate actions for a firmware update:

    Customer Design StatusCustomer Deployment TimeframeRecommended Actions
    Intel® Stratix® 10 FPGA designs in productionFor devices deployed before the end of Q2’19
    • Bitstream regeneration is optional.
    • No adverse impact from regenerating the bitstream if you want a single POF.
    • Optionally download the patch to regenerate the bitstream.
    For devices deployed after the end of Q2’19
    • Bitstream regeneration is required.
    • Firmware update applies optimized on-chip voltage regulator trim settings that improve timing correlation, to accommodate future natural manufacturing variations.
    • Download the patch to regenerate the bitstream or migrate to the Intel® Quartus® Prime Pro Edition Software version newer than 18.1.2 (includes updated firmware) by end-Q2’19.
    Designs not in productionAll devices
    • Download the patch to regenerate the bitstream or migrate to the Intel® Quartus® Prime Pro Edition Software version newer than 18.1.2 (includes updated firmware).

     

    Steps to regenerate bitstream

    1. For the full Intel® Quartus® Prime Pro Edition Software, download and install the patch for the relevant Intel® Quartus® Prime Pro Edition Software version.
    2. If you use standalone Intel® Quartus® Prime Software Programmer Pro Edition, also download and install the patch for the relevant Intel® Quartus® Prime Programmer Pro Edition version.
    3. JTAG users:

    a. Use the existing .sof.

    b. Use programmer from the full Intel® Quartus® Prime Pro Edition Software installed with a patch OR standalone programmer installed with a patch to program the FPGA.

    1. Non-JTAG users: Use the Programming File Generator tool from full Intel® Quartus® Prime Pro Edition Software OR Standalone Programmer installed with the relevant patch to convert your existing .sof to the new .pof/.rbf/.jic/.rpd.
    2. The patch will also take effect on the auto programming file generation feature available in the Intel® Quartus® Prime Pro Edition Software during design compilation.

    Patches

    For the Intel® Quartus® Prime Pro Edition Software released prior to version 18.0.1, final models are not available. You must recompile with a newer version of the Intel® Quartus® Prime Pro Edition Software.

    Download and install the following patch for the full Intel® Quartus® Prime Pro Edition Software:
