Retiming and resynthesis: optimizing sequential networks with combinational techniques
Sharad Malik, Ellen M. Sentovich, Robert K. Brayton, Alberto Luigi Sangiovanni-Vincentelli · 2002
A technique is proposed for optimizing a sequential network by moving the registers to the boundary of the network using an extension of retiming, resynthesizing the combinational logic between the registers using existing logic minimization techniques, and replacing the registers throughout the network using retiming algorithms. A sliding-window optimization technique that considers a large number of different combinational blocks is proposed and demonstrated. The theoretical formulation and results on which the approach is based are given.>
