New ContributorUnfortunately, my problem is slightly more complex and, somehow, the opposite one. Quartus uses one DSP to implement the product, but it wastes the possibility of implementing the addition inside the DSP.
I’ve tried this:
attribute multstyle of res : signal is "dsp";
But Quartus uses 1 DSP plus 17 ALM. The latter could be saved, in my opinion.
I think there must be a way to do it. I’ve tried with Vivado and the addition is performed inside the DSP, that is, one DSP and no LUTs. There should be a way to suggest Quartus to do the same.
