In this paper, we focus on EM models of HFSS, present discovery of intrinsic port inductance in an HFSS model and discuss issues and techniques on how to handle lumped SMT ports in an HFSS EM model for more accurate SMD circuit simulation. b) Defining Integration Line An integration line needs to be specified to define a port mode.
