Guidelines for Estimating Power
The following guidelines are meant to represent worst-case scenarios; they can be generally used to predict the upper
limits of power dissipation:
Logic Modules (m) = 20% of modules
Inputs Switching (n) = Number inputs/4
Outputs Switching (p) = Number of outputs/4
CLKA Loads (q1) = 20% of R-cells
CLKB Loads (q2) = 20% of R-cells
Load Capacitance (CL) = 35 pF
Average Logic Module Switching Rate (fm) = f/10
Average Input Switching Rate (fn) =f/5
Average Output Switching Rate (fp) = f/10
Average CLKA Rate (fq1) = f/2
Average CLKB Rate (fq2) = f/2
Average HCLK Rate (fs1) = f
HCLK loads (s1) = 20% of R-cells
To assist customers in estimating the power dissipations of their designs, Actel has published the eX, SX-A and RT54SX-S
