Hi there,
I have a question about ICM_MLM model when correlate
the model with field solver.
Reading the ICM-1.0, for models of type MLM, sparse
inductance matrix, based on partial inductance
concept, and sparse capacitance matrix will be
generated for circuit simulation.
My question is: the partial inductance concept is
based on unknown current loop, while using EM field
solver, a source has to be defined between the I/O and
GND. In this case, how could we correlate the EM
solution with the MLM model?
One step further, if I want to simulate a GND net or a
VCC net in a multi-layer chip package, which has
several pins connected solid planes, how can I run a
simulation if I want to retrieve the partial
inductance of the GND net or the VCC net separately?
Thanks for any thoughtful inputs.
-Xin
