[FPGA] Feedback node vs shirt register

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

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.
