Why do I see unexpected results from a PR region after I reconfigure an adjacent PR region in SCRUB mode?

Environment

  • Quartus® II Subscription Edition
  • BUILT IN - ARTICLE INTRO SECOND COMPONENT
    Description

    Due to a problem in the Quartus® II software version 13.0 and earlier, when you reconfigure a Partial Reconfiguration (PR) region using SCRUB mode, a nearby or adjacent PR region may be affected. This problem affects designs targeting Stratix® V devices and using multiple PR regions in SCRUB mode. The problem may occur regardless of the number of columns separating the regions.

    Resolution

    A patch is available to fix this problem for the Quartus II software version 13.0. Download and install patch 0.33 from the appropriate link below:

    The patch is generally needed in for Partial Reconfiguration in SCRUB mode. Note that PR regions must be separated by at least one column in order to use SCRUB mode.

    Do not install this patch if you are using the AND/OR programming mode.

    This problem is scheduled to be fixed in a future release of the Quartus II software.
