The practical performance of a PCB design layout depends on a multitude of factors, many of which can be predicted, to a reasonable degree, through a range of PCB design analysis tools such as post-layout Signal Integrity analysis. What's often neglected however, or simply relegated to a 'rule of thumb' methodology, is developing the most effective layout design for board's DC Power Delivery systems. This is the judgment applied to the design of a board's copper areas that provide both the DC supply rails to the circuitry, and their ground or common return path to the DC supply source. The desired outcome is an efficient design that maintains the integrity of the design's DC power layout.With modern digital designs featuring high-speed circuitry, multiple devices, densely populated boards and multiple supply rails, the demands placed on a design's DC power distribution network warrants a more analytical approach to its design. The DC analysis of a Power Delivery Network (PDN), or the results of its DC Power Integrity (PI-DC), is basically aimed at ensuring that adequate copper has been provided in the path from the voltage sources to the loads – in other words, that the planes, traces and vias on the board are of sufficient size (and characteristics) to meet the power consumption requirements of the devices on the board.Fortunately, the guesswork can be removed from the assessment of a PCB's power delivery network (PDN) through the use of a DC Power Integrity (PI-DC) simulation tool, which analyzes a board design's DC performance based on its electrical and physical properties. Such a tool is now available for Altium Designer as the Altium PDN Analyzer powered by CST® (Computer Simulation Technology).Provided as a downloadable Altium Extension application, the PDN Analyzer integrates directly with Altium Designer to allow PI-DC simulation and analysis of the current PCB project. Since the PDN Analyzer functions within Altium Designer there are no manual data import/export requirements, data conversions or separate applications to be run – simply start the PDN Analyzer from the Schematic or PCB editor, set the desired test parameters and run the simulation. The results are primarily delivered through 2D/3D modeling of the circuit board copper layout, allowing a quick assessment of the results and the opportunity to perform exploratory 'what if' testing of the PCB layout design.

Form factor. The Altium PDN Analyzer provides accurate information about a design’s DC power distribution suitability in an easy-to-use and straightforward manner to enable designers to make the most efficient power distribution designs possible.Not only are the results suitable for final design verification, but they can also be used in the planning stages of a design to architect power delivery as efficiently as possible in advance. PI-DC is an invaluable tool in achieving the most efficient and robust power delivery network possible, the PDN Analyzer makes running that simulation and analysis process straightforward, intuitive and efficient.Among these and other advantages that the PDN Analyzer brings to your PCB designs, it also delivers the following benefits: Product reliability: Helps to ensure the correct performance of individual supplies within the design, in terms of standing voltage levels, voltage stability, and trace heating/damage. Improved PCB layout: Provides information that can be applied in creating the most effective use of board space, and allows the easy identification and correction of problematic high current density areas. Knowledge: No longer rely on a rule of thumb approach or approximate calculations when considering the layout of DC current paths.PDN Analyzer simulationIn its most very basic form, a board layout that will be subject to PI-DC analysis might be composed of a Voltage Regulator source and its load, with interconnecting copper areas of various shapes and track widths. A base circuit example of a power source and load. The base circuit's PCB layout, with a range of copper shapes and traces connected by layers and vias.The PDN Analyzer panel interface (Tools » PDN Analyzer) visually emulates a Power Source to Load circuit net that incorporates tangible Power and Ground paths – much as shown in the above circuit and also the conceptual block diagram (Fig. 1). The application automatically extracts all physical and electrical information (netlist, devices and layer shapes, etc) from the currently active PCB design, which provides data for the PI-DC simulation engine. The PDN Analyzer panel interface showing a PI simulation setup for the basic circuit and board layout.Here, the voltage source is the output of U1 (5V between pins 3 and 2), and the load is a specified current through RL (0.1A). Once the initial parameters have been entered via the interface (source/load voltages and currents, etc) and the simulation has been run, the resulting analysis data is graphically modeled in the PCB editor as a rendered 2D or 3D image. The Voltage Drop simulation results for the board's PWR and GND nets copper (U1 to RL, and RL to U1).The PDN Analyzer PI simulation can be set to show Voltage (IR Drop, above image) or Current Density (below image) results for all applicable board layers. The Current Density map for both the PWR and GND nets (U1 to RL). ► See the PDN Analyzer example guide for a complete description of using the PDN Analyzer and interpreting its results.The PDN Analyzer installation includes Altium's SpiritLevel-SL1 PCB reference project with a number of PDN. 21 definitions of PDN.

As you would expect, the IR issues will increase in complexity with the number of loads on the supply through interaction in the power and ground copper paths. Figure 1: A basic block diagram of the power and ground shapes, and the applied loads.Figure 1 (above) shows a simple block diagram of a circuit's power source, and its power and ground shapes (traces and planes) that deliver power to the various loads (memory, microcontrollers, etc.). Note that all the loads are tied to the same power and ground shapes, and depend on those shapes to provide their operating voltage(s). In general, we tend to assume that those power and ground shapes have 0Ω resistance, which isn’t necessarily true, and that assumption can cause problems. Because relatively large currents are often involved, even small resistances in the power and ground shapes can cause significant power consumption (loss) and voltage drops. Figure 2: 'IR Drop' effectsFigure 2 demonstrates an example of the problems that can arise if the resistance of the power and ground shapes are not properly considered. Even though each shape has a relatively small resistance of only 0.25Ω, they have caused the voltage at the load to drop from 5V to 4.5V. The designer has to be aware of this drop and ensure it can be accommodated, or change the design to lessen it, to ensure that that the final design will not fail in the field.The problem, however, seems easy to solve – simply make the power and ground shapes short or large enough to represent an insignificant resistance, using the following relationship: R = ρ * L/A, where: R is the total resistance of a shape (trace or plane) ρ is the resistivity of the material used for the shape (typically copper, ρ ≈ 1.7µΩ-cm) L is the length of the shape A is the cross-section area of the shape (width x thickness)Put simply, if you make your power and ground shapes short, thick and wide, you will minimize their resistance.The difficulty with that, however, is that overly large shapes consume valuable routing space and may limit the amount of Free jCheckers is a Java checkers program, based on my Java Checkers EnginejCheckers is a Java checkers program, based on my Java Checkers Engine that is also used in Checkers Tutor for Android.
