Does the Intel® Stratix® 10 FPGA Firmware apply optimized...

Critical Issue

Description

Intel® Programmable Solutions Group (PSG) has determined that Stratix® 10 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 Firmware, with optimized on-chip voltage regulator trim settings that restore the timing model correlation. Intel® PSG 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.

Recommended Actions

Intel® Stratix® 10 designs in production

For devices deployed before the end of Q2’19

For devices deployed after 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.

· 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

1. Use the existing .sof

2. 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

1. 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, the user must recompile with the newer version of the Intel® Quartus® Prime Pro Edition Software.
