I haven't used either in the last year or two, so a lot may have changed, although, in the past, many of the low end parts had a built-in (slow) PCIe Gen 1 block, so only wrappers were needed to use it, no licenses. IIRC, this was (one of) the problems with the Lattice board, because with no built in endpoint, you needed to license an expensive "softcore" PCIe block (or write your own...) The same is true of 1/10/40G MAC blocks.
