3.12. Failure on Row Y59 When Using the Error Detection Cyclic Redundancy Check (EDCRC) or Partial Reconfiguration (PR)

When the error detection cyclic redundancy check (EDCRC) or partial reconfiguration (PR) feature is enabled, you may encounter unexpected output from clocked components such as flip-flop or DSP or M20K or LUTRAM that are placed at row 59 in Intel® Arria® 10 SX devices.

This failure is sensitive to temperature and voltage.

Intel® Quartus® Prime software version 18.1.1 and later displays the following error message:
  • In Intel® Quartus® Prime Standard Edition:
    • Info (20411): EDCRC usage detected. To ensure reliable operation of these features on the targeted device, certain device resources must be disabled.
    • Error (20412): You must create a floorplan assignment to block out the device resources at row Y=59 and ensure reliable operation with EDCRC. Use the Logic Lock (Standard) Regions Window to create an empty reserved region with origin X0_Y59, height = 1 and width = <#>. Also, review any existing Logic Lock (Standard) regions that overlap that row and ensure if they account for the unused device resources.
  • In Intel® Quartus® Prime Pro Edition:
    • Info (20411): PR and/or EDCRC usage detected. To ensure reliable operation of these features on the targeted device, certain device resources must be disabled.
    • Error (20412): You must create a floorplan assignment to block out the device resources at row Y=59 and ensure reliable operation with PR and/or EDCRC. Use the Logic Lock Regions Window to create an empty reserved region, or add set_instance_assignment -name EMPTY_PLACE_REGION "X0 Y59 X<#> Y59-R:C-empty_region" -to | directly to your Quartus Settings File (.qsf). Also, review any existing Logic Lock regions that overlap that row and ensure if they account for the unused device resources.
Note: Intel® Quartus® Prime software versions 18.1 and earlier do not report these errors.

Workaround

Apply the empty logic lock region instance in the Quartus Prime Settings File (.qsf) to avoid use of row Y59. For more information, refer to the corresponding knowledge base.
