Hi all:
Is there any Hybrid EM & circuit simulator?
As you all know, EM solvers (FEM,FDTD,MOM)
try to solve PDE (Partial Diff. Equation-- Maxwell Equation).
SPICE like simulators (HSPICE, PSPICE..) are
solveing ODE (Ordinary Differential Equation).
Instead of geting Frequency domain data (S-parameter)
and do macromodeling to export to SPICE, do
people solve them at one shoot?
FDTD can include lumped elements, but
that is not what I am talking about.
I am saying given a system model with
A) lumped networks
B) EM structures
C) Nonlinear devices
can a general solver solve it?
So final challege:
Is there a hybrid Nonlinear PDE & ODE solver/algorithm?
Thanks
