I haven't used Designware recently but I'd be very surprised if they
added memory inferring to its features. In ASICs one needs to run a
memory compiler which is specific to each process and it's supplied by
the library vendor (or another third party memory IP vendor). So you
probably will have to run a memory compiler get a model and
instantiate that model in your design. If so it makes more sense to do
the same for the FPGA flow too.
