To calculate the active power dissipated from the complete design, the switching frequency of each part
of the logic must be known. EQ 4 shows a piece-wise linear summation over all components.
Power =VCC2 * [(m * CEQM * fm)modules + (n * CEQI * fn) inputs
+ (p * (CEQO+ CL) * fp)outputs
+ 0.5 * (q1 * CEQCR * fq1)routed_Clk1 + (r1 * fq1)routed_Clk1
+ 0.5 * (q2 * CEQCR * fq2)routed_Clk2 + (r2 * fq2)routed_Clk2
EQ 4
Where:
m = Number of logic modules switching at fm
n = Number of input buffers switching at fn
p = Number of output buffers switching at fp
q1 = Number of clock loads on the first routed array clock
q2 = Number of clock loads on the second routed array clock
r1 = Fixed capacitance due to first routed array clock
r2 = Fixed capacitance due to second routed array clock
CEQM = Equivalent capacitance of logic modules in pF
CEQI = Equivalent capacitance of input buffers in pF
CEQO = Equivalent capacitance of output buffers in pF
CEQCR = Equivalent capacitance of routed array clock in pF
CL = Output lead capacitance in pF
fm = Average logic module switching rate in MHz
fn = Average input buffer switching rate in MHz
fp = Average output buffer switching rate in MHz
fq1 = Average first routed array clock rate in MHz
fq2 = Average second routed array clock rate in MHz
