The numbers in this table are based on the conditions set forth in
Quiescent supply current is measured with all I/O drivers in a high-impedance state and with all pull-up/pull-down resistors at the I/O pads

file (that is, a design with no functional elements instantiated). For conditions other than those described above (for example, a design
including functional elements), measured quiescent current levels will be different than the values in the table.
There are two recommended ways to estimate the total power consumption (quiescent plus dynamic) for a specific design: a) The
Spartan-3A FPGA XPower Estimator
Analyzer uses a netlist as input to provide maximum estimates as well as more accurate typical estimates.
The maximum numbers in this table indicate the minimum current each power rail requires in order for the FPGA to power-on successfully.
For information on the power-saving Suspend mode, see XAPP480: Using Suspend Mode in Spartan-3 Generation FPGAs. Suspend mode
typically saves 40% total power consumption compared to quiescent current.
