Logical Effort and Parasitic Delay Calculation for Multi-Stage Logic Chains
Logical effort theory defines a gate's input capacitance relative to a reference inverter with symmetric swing (2C), quantified by logical effort ($G$) and parasitic delay ($P$). Path electrical effort ($H$) represents the output-to-input load ratio normalized by drive strength, while stage effort is the product of these factors used to determine optimal sizing. This framework belongs to Digital IC Design theory for minimizing propagation delay through multi-stage logic chains under Elmore delay constraints without relying on specific circuit implementations or empirical datasets.
