Altera recommends that you use separate layers for signals, the ground
plane, and voltage supply planes. You can support separate layers by
using multi-layer PCBs, assuming you are using two signal layers.
Figure 12–18 shows how to use regulators to generate 1.5-V and 2.5-V
power supplies if the system needs two power supply systems. One
regulator is used for each power supply.
Figure 12–18. Two Regulator Solution for Systems that Require 5.0-V, 2.5-V and 1.5-V Supply Levels
Figure 12–19 shows how to use a single regulator to generate two
different power supplies (1.5-V and 2.5-V). The use of a single regulator
to generate 1.5-V and 2.5-V supplies from the 5.0-V power supply can
minimize the board size and thus save cost.
