CAN Network Signaling

This 4-node CAN network model is an extensible platform for analyzing network signal quality. The network configuration can be easily modified to represent multiple design variants. This can include transmission line lengths and characteristics, termination impedance and placement, transceiver drive strength and edge-rates, etc. New nodes can easily be added. All of these configurations can be simulated and signal integrity verified.

In the particular configuration shown, the parasitic capacitance at Node 4 causes asymmetric transitions. This asymmetry would normally result in EMI-causing even-mode propagating currents on the transmission lines, but the choke greatly reduces this effect.
