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:
Logic Modules (m)
Inputs Switching (n)
Outputs Switching (p)
First Routed Array Clock Loads (q
1
) =
= Number of logic modules switching at f
m
= Number of input buffers switching at f
n
= Number of output buffers switching at f
p
= Number of clock loads on the first routed array
clock
= Number of clock loads on the second routed
array clock
= Fixed capacitance due to first routed array
clock
= Fixed capacitance due to second routed array
clock
= Fixed number of clock loads on the dedicated
array clock = (528 for A54SX16)
= Equivalent capacitance of logic modules in pF
= Equivalent capacitance of input buffers in pF
= Equivalent capacitance of output buffers in pF
= Equivalent capacitance of routed array clock in
pF
= Equivalent capacitance of dedicated array
clock in pF
= Output lead capacitance in pF
= Average logic module switching rate in MHz
= Average input buffer switching rate in MHz
= Average output buffer switching rate in MHz
= Average first routed array clock rate in MHz
= Average second routed array clock rate in MHz
