Split-Plane Method
The split-plane design method reduces the number of planes required by
placing two power supply planes in one plane (see
example, the layout for this method can be structured as follows:
■
■
This technique assumes that the majority of devices are 2.5-V. To support
MultiVolt I/O, Altera devices must have access to 1.5-V and 2.5-V planes.
With the proliferation of multiple voltage levels in systems, it is
important to design a voltage system that can support a low-power
device like Cyclone devices. Designers must consider key elements of the
PCB, such as power supplies, regulators, power consumption, and board
layout when successfully designing a system that incorporates the low-
voltage Cyclone family of devices.
