then the design that uses the io_ddr has hdl_lib_uses = io_ddr in its hdllib.cfg whereas the design that does not
use io_ddr should in have hdl_lib_uses = io_ddr_empty, where io_ddr_empty is a revision of io_ddr with only the
entity and an emtpy architecture.
+ If only the testbench uses some IO IP and the DUT does not (eg like for the reorder library where the tb can use

+ synthesis.
