Note: transistors and variable resistance packages may have pins that do not match actual components, and when they are loaded, they cannot find nodes.
When the two elements are present in the circuit, the difference between PCB and SCH is modified. The fastest way is to generate the network table directly in the network table,
Switch the transistor pin to 1, 2, 3, and change the variable resistance to 1, 2, 3 of the circuit board element.
