Electronic systems show increasing speed, power dissipation and density. The design, manufacture and simulation of a Power Distribution Network (PDN) for such systems become an increasing design challenge. A large number of supply voltages and signaling levels is used, timing and noise margins are reduced. The allowed noise on signals and power supply rails decreases while at the same time the density and bandwidth of interconnections increase. This means that the design of a power distribution network (power integrity) is not independent anymore from the signal integrity and electro magnetic compatibility (EMC) design domains. Power distribution design therefore becomes an important condition for good signal integrity and electromagnetic compatibility. The power distribution of a board is discussed from the perspective of power integrity with minimal mathematics and practical examples.

Electronic designers, board and IC designers, system architects. Educational level: At least BSc in electronics or physics. Prior knowledge on EMC is not required. The focus of the course is on board design and on the interface between the board and its IC’s. IC designers need to know how to interface an IC to a board and on its effect on the power distribution on the board and within the IC.
