RadTolerant FPGAs

v3.1
To calculate the active power dissipated from the complete design, the switching frequency of each part of the logic
must be known. EQ 1-5 shows a piece-wise linear summation over all components. Since the RT1280A and A1280A
have two routed array clocks, the dedicated_Clk and IO_Clk terms do not apply. For all other devices all terms apply.
Power = VCC
2 * [(m * C
EQM* 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 + 0.5 * (s1 * CEQCD * fs1)dedicated_Clk + (s2 * CEQCI * fs2)IO_Clk]
