Computational Analysis of Printed Traces - Full-Wave or Transmission Line Circuit Simulation

This paper explores the simulation of printed circuit board (PCB) traces, which play a crucial role in signal integrity, electromagnetic interference (EMI), and overall system performance. Two primary approaches for analyzing these traces are discussed: full-wave electromagnetic simulations and quasi-static transmission line (QSTL) circuit simulations. Full-wave simulations, based on Maxwell's equations, provide a detailed, physics-based model of electromagnetic interactions, offering high accuracy for high-frequency designs but at a high computational cost. In contrast, the QSTL circuit simulations, which model traces as distributed elements, are computationally efficient and ideal for early design iterations, though they may lack accuracy in high-frequency scenarios. This paper compares both methods, and the detailed study evaluating their accuracy, computational efficiency, and scalability through case studies will be presented in the conference.
