Nets from ECAD are connection among pins of components. Thus, two nets connected to passive device are treated as different nets. In this case, PollEx can handle these two nets as one net as below picture.
If the button is pressed, PollEx searches all nets which is connecting passive device. With those buttons, user can exclude components which user does not want to make composite nets.
If even net of one side of component is power or ground net, PollEx automatically excludes that component from making list. Thus, decoupling capacitor or pull-up / pull-down resistors are automatically excluded.
User can add some specially components to list to make composite net after setting their inner pin connection at list control.
If once composite nets are generated, PollEx save its structure to use at other tools like Net2D/3D viewer, Net Topology Viewer and linking with PCB Explorer or Picking Tool.
