Is it possible to infer wide adders that require multiple DSP48s? In my experiments with Synplify, I found that it will infer a DSP48-based adder when the inputs are up to 36 bits wide, but when I use 37-bit inputs, the adder is synthesized in fabric. Is there a way to get this to work? XST won't do this either, at least according to the user's guide. -Kevin
