You build a signal integrity channel by cascading measured nport S-parameter blocks with lossy transmission lines and lumped parasitics. MATLAB RF Toolbox drives the circuit composition via add() and setports(), then computes S-parameters using sparameters().

Yes, you can model frequency-dependent skin-effect and dielectric loss in MATLAB using the RF Toolbox txlineWRLGC or txlineWtable elements. These allow you to extract insertion loss, return loss, and crosstalk from your PCB trace segments.

You expose and terminate ports for multi-port crosstalk analysis by defining proper port termination and exposure using setports(). This ensures faithful S-parameter extraction for differential or multi-port network topologies.

Yes, MATLAB RF Toolbox supports mixed lumped-distributed topologies. You can combine vias, connectors, PCB segments, and multi-port blocks in a single circuit to evaluate complex interconnect behavior accurately.

The best way to extract insertion loss and return loss is to assemble the cascaded SI channel using add(), configure the ports with setports(), and then compute the S-parameters over your specified frequency range using the sparameters() function.
