To calculate the active power dissipated from the complete design, the switching frequency of each part of the logic

must be known. The equation below shows a piece-wise linear summation over all components.

Power = VCCA2 * [(m x 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 (2)
