Variables

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

Fanout

Fanout is the number of similar gate inputs that a gate output can drive. In other words, it represents the number of gates or loads connected to the output of the current gate.

Symbol: h

Measurement: NAUnit: Unitless

Note: Value should be greater than 0.

Formulas to find Fanout

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

Other formulas in CMOS Special Purpose Subsystem category

Go Fanout of Gate

h = \frac{f}{g}

Go Capacitance of External Load

C out = h \cdot C in

Go Gate Delay

G d = 2^{N sr}

Go Temperature Difference between Transistors

ΔT = Θ j \cdot P chip

How to Evaluate Stage Effort?

Stage Effort evaluator uses Stage Effort = Fanout*Logical Effort to evaluate the Stage Effort, The Stage effort formula is defined as the ratio of the input capacitance of a gate to the input capacitance of an inverter delivering the same output current. Stage Effort is denoted by f symbol.

How to evaluate Stage Effort using this online evaluator? To use this online evaluator for Stage Effort, enter Fanout (h) & Logical Effort (g) and hit the calculate button.

FAQs on Stage Effort

What is the formula to find Stage Effort?

The formula of Stage Effort is expressed as Stage Effort = Fanout*Logical Effort. Here is an example- 3.9984 = 0.84*4.76.

How to calculate Stage Effort?

With Fanout (h) & Logical Effort (g) we can find Stage Effort using the formula - Stage Effort = Fanout*Logical Effort.
