This 4-node CAN (FD) network can be used to verify signal quality for various network configurations specified by the user. Many of the component parameters can be modified to represent network variants. This includes transmission line lengths and electrical properties, termination impedances, transceiver drive strengths and edge-rates, etc.* Just run a new simulation to see the impact on signal quality due to that change.It is particularly interesting to increase the length of one of the stub lines, for example the transmission line going to node2 (lower left), from its nominal 1 meter to perhaps 10 meters. This will cause a complete collapse in data communication! (Look for bit errors in the bottom wave viewer)If the design is copied and saved, then the user can free-form edit the network topology, adding new nodes, lines and other passive or active components. New simulation runs will help the user assess the viability of those network configurations.*Note: The user can also specify the "slow" and "fast" data rates and fixed test patterns, to be transmitted at the beginning of the simulation, on the CAN FD data source (u1, bottom middle), After these fixed patterns are sent, the data source then sends a continuous sequence of random data at the fast data rate, until the simulation ends.
