 The WARP FPGA board does not contain any built-in current measurement capabilities. In order to measure current consumption, the power plane of interest must be driven by an external, off-board supply whose current can be measured. When an external supply is used, the on-board regulator for a given plane must be disabled to avoid a drive fight between the on-board and off-board supplies. Four of the FPGA board's supplies (5v, 3.3v, 2.5v and 1.5v) can be individually disabled. To disable these regulators, simply mount a shunt on the jumper adjascent to the regulator; see the table below for the specific reference designators for each jumper.
+High-current screw terminals are connected to the primary power planes: GND, 12v, 5v, 3.3v and 1.5v and can be used to connect external supplies.

 The MGT power planes (2.5v, 1,8v) cannot be disabled and should never be driven externally.
