Why does the DUPLICATE_HIERARCHY_DEPTH assignment is ignored when used as an altera_attribute?

Environment

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

    Due to a problem in the Quartus® Prime Pro Edition Software version 19.1, the automatic register duplication by hierarchical proximity (DUPLICATE_HIERARCHY_DEPTH) may be ignored when applied with an 'altera_attribute' synthesis attribute.

    Resolution

    To work around this problem, set the DUPLICATE_HIERARCHY_DEPTH assignment in your Quartus® Prime settings file (.qsf).

    set_instance_assignment -name DUPLICATE_HIERARCHY_DEPTH -to <register_name> <num_levels>

     

    This problem is fixed beginning with the Quartus® Prime Pro Edition software version 19.4.
