Calculating Typical Power Dissipation
ProASIC
of both the number of tiles utilized and the system speed. Power dissipation can be calculated using the following
formula:
Total Power Consumption—P
where:
Global Clock Contribution—P
P
for R < 15000 the model is: (P1 + (P2*R) – (P7*R2)) * Fs (lightly-loaded clock trees)
for R > 15000 the model is: (P10 + P11*R) * Fs (heavily-loaded clock trees)
where:

0.00003 µW/MHz is a correction factor for partially-loaded clock trees
device power is calculated with both a static and an active component. The active component is a function
