Critical Issue
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.
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 Status | Customer Deployment Timeframe | Recommended Actions |
Intel® Stratix® 10 FPGA designs in production | For devices deployed before the end of Q2’19 |
|
For devices deployed after the end of Q2’19 |
| |
Designs not in production | All devices |

Steps to regenerate bitstream
- For the full Intel® Quartus® Prime Pro Edition Software, download and install the patch for the relevant Intel® Quartus® Prime Pro Edition Software version.
- 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.
- 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.
- 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.
- 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.
