Is the timing model for Intel® Stratix® 10 1SX040, 1ST040, and 1SG040 devices correct?

Environment

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

    Critical Issue

    Description

    No, due to a problem in the Intel® Quartus® Prime Pro Edition Software v21.2 and earlier, the timing model for Intel® Stratix® 10 1SX040, 1ST040 and 1SG040 devices is not correct. This occurs because the timing model for vertical (C2/C3/C4/C16) routing wires are miscalculated. Errors range from few ps to 50 ps per path, with 150 ps in the worst corner for the worst wire. This problem only affects Intel® Stratix® 10 1SX040 (GX/SX H-Tile) / 1SG040 (TX E-Tile) devices.

    Resolution

    To work around this problem for projects using devices 1ST040xxxx (TX E-Tile), download and install the patch according to the versions of your Intel® Quartus® Prime Software.

    Patch 0.60 for Intel Quartus Prime Pro Edition Software v20.1:

    Patch 0.57 for Intel Quartus Prime Pro Edition Software v20.2:

    Patch 0.74 for Intel Quartus Prime Pro Edition Software v20.3:

    Patch 0.43 for Intel Quartus Prime Pro Edition Software v20.4:

    To work around this problem for projects using devices 1ST040xxxx (TX E-Tile) or 1SX040xxx (GX/SX H-Tile), download and install the patch according to the versions of your Intel® Quartus® Prime Software.

    Patch 0.50  for Intel Quartus Prime Pro Edition Software v21.1:

    Patch 0.30 for Intel Quartus Prime Pro Edition Software v21.2:

    Once the patch is installed, perform the following actions:

    1. Save <design>.sta.rpt before running.
    2. Run quartus_sta –force_dat <project> in the command line.
    3. Recompile the design if there are any negative slacks.

    This problem only affects the timing model for the devices listed. The other Intel® Stratix® 10 devices are not affected.

    This problem is fixed beginning with version 21.3 of the Intel® Quartus® Prime Pro Edition Software.
