Static power consumed by an ALM?

I'm a student researching FPGA related issues. Since an ALM could combine functions into one ALM, the static power it takes might varied from different combinations. The question is, does the st...

Oh...I see...

Thank "thepancake" and "FvM" for replying.

My misunderstanding is that, under different configurations, some transistors may always not be activated (like an ALM only implements a 4-input function). So that it become power gated status (or something like that).

But I still have a question.

Does it mean that no matter how many ALMs used (or configured), the static power of using such device is the same?

That is, the device will always take the same static power no matter how many ALMs the design needs?

i.e.

The static power of design A containing 10 ALMs is equal to the static power of design B containing 50 ALMs.

Assume that all other situations or conditions are the same. (Like# IO, etc.)
