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...

Static power consumption of the FPGA core is mainly caused by the leakage currents involved with nm CMOS technologies. I don't see a reason why loading different configurations into the core ALMs should cause other than very small erratical differences in leakage currents.

The situation is probably different for I/O cells, that can be expected to have a quiescent current, e.g. differntial input amplifiers and true LVDS current sources.
