power required for spartan 3an

[sriharsha.hs]

Hi folks,

I am using spartan 3AN (XC3S50AN-4FTG256) for my design. How should I calculate the power required for running the design in FPGA.?

As per my understandings it requires,

VCCint = 1.2 V.
VCC (AUX) = 3.3 V
VCCO (Output supply Voltage)
GND

All pins need to be connected.

Is my understandings are correct because ?

Is it possible to reduce the no of pins connected depending upon the resource used inside the FPGA.?

Any reply accepted.

Thank you.

you can use xpower software which comes with ise webpack for measuring the power of your design.
