Setting up a multi-network PDN analysis by defining sources and loads in your PDN.Īny PDN analysis tool should help you determine how multiple PDNs interact with each other. The typical structure of a PDN is hierarchical voltage and current density can be examined throughout each level in the network, or within individual power nets. The image below shows how to set up a simultaneous multi-network simulation for examining the DC voltage and current density distribution in an entire PCB. To get started with PDN analyzer, simply bring up the PDN Analyzer window and define the structure of your PDN. Take a look at our guide to getting started with PDN Analyzer and how you can visualize your voltage and current density distribution in your PCB.ģD visualization of current density in a PCB with the PDN Analyzer Getting Started with PDN Analyzer You’ll be able to see power nets alone, or as a rendered overlay against the complete PCB in 2D or 3D. With PDN Analyzer, results are displayed in a replica of your PCB layout, which is generated using your layout data in Altium Designer’s PCB Editor. Whether you are a seasoned power integrity expert or a beginner, gaining insight into your design’s voltage and current density distribution, current direction, and hot spots is simple and intuitive. PDN Analyzer’s unique voltage regulator models (VRMs) enable these interactions to be captured while simplifying setup and increasing simulation speed. Voltages and current density on the power and ground nets are functions of all PDNs in your PCB, and these quantities are unidentifiable when each PDN is examined in isolation. The right PDN should take data directly from your PCB layout, and it should show you the voltage and current density distribution in your PDN. If you want to maximize your productivity, you need a software package that integrates your power integrity simulator into your PCB design software. Maintaining stable voltages and suppressing noise ensures your PCB will operate as designed. Power integrity and signal integrity are some of the most important aspects in many PCBs. A unified PCB design software package that contains all the design and PDN analysis tools you need to build advanced electronics.
