WebFlip-Flop and Clock Design R. Saleh Dept. of ECE University of British Columbia [email protected] RAS Lecture 6 2 Design Considerations • Basic role of clock is to perform synchronization operation in sequential logic circuits • Clocks are used primary to drive the flip-flops in a logic chip • Usually thousands of flops exist on the chip WebFeb 16, 2024 · Retiming is a sequential optimization technique to move registers across combinatorial logic to improve the design performance without affecting the input/output behavior of the circuit. The circuit shown in Figure 1 has a critical path with a 6-input adder. The path highlighted in red is the path that limits the performance of the whole circuit.
WebJun 28, 2004 · FIG. 4g illustrates the last forward retiming where flip-flop 238 (FIG. 4f) is retimed to the last black box 240 (FIG. 4f), as flip flop 242 (FIG. 4g). Described embodiments provide techniques to verify a synthesis and retiming operation by adding black boxes to the design specification and then processing the black boxes in the retimed ...

Webditional retiming, flip-flops may he placed on any edge. In order to avoid flip-flops being placed on the edges we intro- duced in timing models, we require that the retiming tags of the input and the output connected by such an edge be the same. This means that the number of Hip-flops moved over the input is the same as the output.
WebRetiming is an optimisation technique which relocates flip-flops in a network while preserving the functionality of the network.
