[Tech Tips Simcenter Flotherm XT] PCB electrothermal analysis - HyperLynx PI co-simulation

Learn how to perform PCB electrothermal modeling using HyperLynx PI, power integrity simulation software, and Simcenter Flotherm XT, CAD centric electronics cooling CFD software, in a co-simulation that accurately represents board copper trace power dissipation by modeling electrical resistance changes vs temperature. This capability was released in Simcenter Flotherm XT Version 2020.2, utilizing the Material Map PCB thermal modeling approach for efficient thermal simulation of multilayer PCBs. It operates with HyperLynx release Vx2.8 and above for DC drop analysis co-simulation. Using these Siemens Xcelerator portfolio tools easily together, a closer ECAD – MCAD electrothermal co-design method is possible. This video also illustrates updating a PCB thermal model quickly using Simcenter Flotherm XT EDA Bridge (which can handle EDA files like ODB , CCE, IPC-2581). During the co-simulation, temperature results are passed into a DC drop analysis to better model copper electrical resistance changes with tempera
