1. A computer-implemented method for use in an electronic design environment comprising:
receiving, using at least one processor, an electronic design layout;
performing parasitic extraction on the electronic design layout;
extracting an electromagnetic model from the electronic design layout;
reconnecting at least one coupling capacitor associated with a net of the electromagnetic model;
performing a simulation including the reconnected at least one coupling capacitor, wherein reconnecting at least one coupling capacitor includes reconnecting to an electromagnetic simulator network prior to solving for one or more s-parameters;
defining one or more trace through cells, wherein a trace through cell is defined using at least one of a text file, an environmental variable, net tracing, or DC path information;
automatically detecting the one or more trace through cells; and
reconnecting a capacitance for one or more embedded nets that connect to the trace through cells.
