[FPGA] Feedback node vs shirt register

[Raf@Tecnora]

Hi All,

a very simple and probably not so original question.

When working with FPGA, if line feedback is needed inside a while loop, what are the pros and cons among feedback nodes and shift registers?

Are there notable differences in terms of area/resources use?

Thank you

Raf

Semantic differences only, there's no actual fabric difference for similarly configured Shift Regsiters or Feedback Nodes

I see what you did there.

It's just a matter of ironing out the bugs. 🙂

That was awesome.  I wish I could give more than one kudo for that one.
