You can force control set mapping by applying the DIRECT_RESET / DIRECT_ENABLE / EXTRACT_RESET / EXTRACT_ENABLE attributes as needed to handle the mapping of control sets for a given structure.

When the design includes a synchronous reset/enable, synthesis creates a logic cone mapped through the CE/R/S pins when the load is equal to or above the threshold set by the -control_set_opt_threshold synthesis switch, or creates a logic cone that maps through the D pin if below the threshold. The default threshold for Versal adaptive SoC is 2.
