how to force the quartus to use Input Register Bank in DSP

I implemet multiplier in dsp block with sampled inputs. i expect that the sampled input will be implemented in the Input Register Bank in the DSP block, but unfortunately the registers located out of the DSP block.

I would like to know how to force the quartus to do this?

Thanks Gilad

    Hi Gilad, As I understand it, you have some inquiries related to the input register of DSP. To ensure we are on the same page, would you mind to share with me a simple test design together with some screenshots of your observation so that I can have further understanding of your observation. thank you.

      I implemeted complex multiplication with pipelined inputs, it consuming 2 DSPs . I want to reduce dedicated logic registers by storing data inside DSP registers. I wouls like to know way to achive this?
