Physics-based simulation tools offer an efficient alternative to full-wave solvers for predicting the signal integrity behavior of PCB interconnects. By leveraging simplified analytical models of the underlying electromagnetic phenomena, they achieve significantly lower computation times while maintaining accurate results — currently for frequencies up to 40 GHz. However, as modern high-speed applications push data rates ever higher, these simplified models reach their limits: the electromagnetic behavior becomes increasingly complex, and effects that were previously negligible can no longer be ignored. To address this, my research investigates the extension of physics-based tools to frequencies up to 100 GHz by developing refined models that capture this additional complexity — such as more accurate descriptions of the electromagnetic field behavior around via structures and their mutual interactions. Where purely analytical descriptions become impractical, data-driven or numerical methods are explored to complement the modeling approach.
