Measurement: NAUnit: Unitless

Note: Value should be greater than 0.

Formulas to find Fanout

Stage Effort

Stage effort is a measure of how much effort (or delay) is required to drive the output of a logic gate or circuit to the next stage in the design.

Symbol: f

Measurement: NAUnit: Unitless

Note: Value should be greater than 0.

Formulas to find Stage Effort

Logical Effort

Logical effort is a metric that represents the intrinsic speed of a logic gate.

Symbol: g

Measurement: NAUnit: Unitless

Note: Value should be greater than 0.

Formulas to find Logical Effort
