DCIRESET is an AMD design primitive that provides the capability to perform a reset of the DCI controller state machine during normal operation of the design. This primitive is required in a design when DCIUpdateMode is set to QUIET (see DCIUpdateMode Configuration Option ) or for the case outlined in Special DCI Requirements in Some Banks . See the UltraScale Architecture Libraries Guide (UG974) [Ref 5] for more details on the DCIRESET primitive.
