  2. Use following aggressive implementation strategies options
    1. set_property STEPS.PHYS_OPT_DESIGN.ARGS.DIRECTIVE AggressiveExplore [get_runs implementation_*]
    2. set_property STEPS.ROUTE_DESIGN.ARGS.DIRECTIVE AggressiveExplore [get_runs implementation_*]
    3. set_property -name {STEPS.ROUTE_DESIGN.ARGS.MORE OPTIONS} -value -tns_cleanup -objects [get_runs implementation_*]
    4. set_property STEPS.POST_ROUTE_PHYS_OPT_DESIGN.IS_ENABLED true [get_runs implementation_*]
    5. set_property STEPS.POST_ROUTE_PHYS_OPT_DESIGN.ARGS.DIRECTIVE Default [get_runs implementation_*]
