Stability of a hybrid FDTD-circuit model for on-chip power-grid switching analysis

Research output: Contribution to journalArticlepeer-review


A circuit model for the package-to-chip power grid interface is presented for use in conjunction with the finite-difference time-domain (FDTD) simulation of on-chip power-grid switching. A numerical scheme is proposed for the integration of the hybrid circuit/FDTD model, the stability of which is dictated by the CFL condition for the FDTD grid and thus is independent of the specific values of the circuit elements in the lumped model. Numerical experiments are performed to demonstrate the numerical stability of the model and its accuracy.
