Abstract :
The concepts of corolla partitioning based on an analysis of signal reconvergence to cyclic sequential circuits are extended. The sequential circuit is partitioned into corollas that will contain latches but can be peripherally retimed and resynthesized using combinational techniques. Cycles are broken in the circuit by ensuring that the partitions that are formed are acyclic. Application of the proposed partitioning, retiming and resynthesis approach to a set of large sequential benchmarks has shown considerable gains after resynthesis
