Equivalent Capacitance
The power dissipated by a CMOS circuit can be expressed by
the Equation 1.
Power (uW) = CEQ * VCC2 * F
(1)
Where:
CEQ is the equivalent capacitance expressed in pF.
VCC is the power supply in volts.
F is the switching frequency in MHz.
Equivalent capacitance is calculated by measuring ICCactive
at a specified frequency and voltage for each circuit
component of interest. Measurements have been made over a
range of frequencies at a fixed value of VCC. Equivalent
capacitance is frequency independent so that the results may
be used over a wide range of operating conditions. Equivalent
capacitance values are shown below.
CEQ Values for Actel FPGAs
To calculate the active power dissipated from the complete
design, the switching frequency of each part of the logic must
be known. Equation 2 shows a piece-wise linear summation
over all components.

Determining Average Switching Frequency
To determine the switching frequency for a design, you must
have a detailed understanding of the data input values to the
circuit. The following guidelines are meant to represent
worst-case scenarios so that they can be generally used to
predict the upper limits of power dissipation. These
guidelines are as follows:
