I implemet multiplier in dsp block with sampled inputs. . I would like to know how to force the quartus to do locate the input register in the DSP?

Hi Gilad, As I understand it, there is a another thread (04074752) which look similar with this. Just would like to check with you if both are referring to the same issue? If not, please feel free to share further details on this case ie test design and screenshots for further understanding. Thank you.
