TUMA2: Shift Left your Signal Integrity -- Automated SI-Driven PCB Optimization with GenAI

Abstract
Modern high-speed designs face a common bottleneck: the combinatorial explosion of via transitions and other structures in a variety of complex stackups. With limited engineering resources and schedule constraints, manually optimizing the stackup and structures to meet stringent requirements can become an impossible task, forcing suboptimal outcomes including limiting decisions that impact product cost. This talk shares a programmatic solution using parametric design in JITX and closed-loop simulation with Ansys HFSS to accelerate RF SI optimization, beginning at pre-layout. How AI is leveraged is a focus.
