发明名称 System and method of replacing flip-flops with pulsed latches in circuit designs
摘要 A circuit design system, methodology, and software are disclosed for generating circuit capable of consuming less dynamic power. In particular, the circuit design methodology entails modifying an initial circuit design including a clock network coupled to a plurality of edge-triggered flip-flops to generate a modified circuit design that uses pulsed latches driven by pulse generators in place of at least some of the flip-flops. Since pulsed latches use less dynamic power than edge-triggered flip-flops, the modified circuit may consume less dynamic power. The circuit design methodology may further entail adding delay cells for balancing the clock network to compensate for timing effects caused by the insertion of pulse generators. Additionally, the methodology may further include cloning of forbidden clock paths to make more flip-flops eligible for pulsed latch replacement.
