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?

Description

Intel® Programmable Solutions Group (PSG) 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® Programmable Solutions Group 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 designs in production	For 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.
Intel® Stratix® 10 designs in production	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 production	All 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 Programmer Pro Edition, also download and install the patch for the relevant Intel® Quartus® Prime Programmer Pro Edition version.

3. JTAG users

Use the existing .sof.
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.

4. 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.

5. 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 the 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:

Download and install the following patch for the standalone Intel® Quartus® Prime Programmer Pro Edition:

The updated Intel® Stratix® 10 FPGA firmware is scheduled to be included in a future release of the Intel® Quartus® Prime Pro Edition Software.
