Technical Documentation PDN Analyzer（由 CST 提供） For the latest DC Power Integrity analysis functionality, take a look at Altium's Power Analyzer by Keysight. The PDN Analyzer powered by CST® (Computer Simulation Technology) 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…

Technical Documentation PDN Analyzer（由 CST 提供）示例指南 The PDN Analyzer (PDNA) application is relatively straightforward to use, and basically involves setting up the PI-DC simulation net parameters, running the simulation and then interpreting the results. The data used in a PDN Analyzer power net simulation is drawn directly from the currently loaded PCB design project, which can be iteratively edited to improve the power integrity of the supply…
