For non -2LE devices, where VCCINT, VCCBRAM, VCCINT_IO, and VCCINT_GT are all on one common plane, the voltage regulator module (VRM) power output does not need to change versus the VU13P device. However, for -2LE devices VCCINT_GT consumes up to 12W of power. This extra 12W must be accounted for on the common VCCBRAM/VCCINT_IO/
VCCINT_GT plane. Likewise, the VCCINT VRM can be downward sized by approximately 12W.
