Register Duplication for Timing Closure

Register Duplication for Timing Closure



The attached document describes different methodologies for duplicating registers to help with timing closure. Topics include:

- Why do registers with large fan-outs have worse timing(it's not due to loading)

- Physical Synthesis Register Duplication

- Max Fan-out

- Manual Logic Duplication

- Pros and cons of doing this in RTL or through assignments

- Analysis of a real design with various techniques(I have not attached the design, but have critical path screen-shots)
