can be combined with frequency and voltage to represent
active power dissipation.
E qui v a l ent C apac i t ance
The power dissipated by a CMOS circuit can be expressed by
Equation 1:
Power (uW) = CEQ * VCC
2 * F
(1)
where:
Equivalent capacitance is calculated by measuring ICCactive
at a specified frequency and voltage for each circuit
component of interest. Measurements are made over a range
of frequencies at a fixed value of VCC. Equivalent capacitance
is frequency independent so that the results can be used over
a wide range of operating conditions. Equivalent capacitance
values are shown below.
CE Q Val ues f o r Act e l FP G A s
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 piecewise linear summation
over all components that applies to all ACT 1, 1200XL,
3200DX, ACT 2, and ACT 3 devices. Since the ACT 1 family has
only one routed array clock, the terms labeled routed_Clk2,
dedicated_Clk, and IO_Clk do not apply. Similarly, the ACT 2
family has two routed array clocks, and the dedicated_Clk
and IO_Clk terms do not apply. For ACT 3 devices, all terms
will apply.
