Circuit type recognition

Power and ground signals

When a net has been identified as power net the recognized voltage is shown between parenthesis after the signal name and a power icon is displayed in the circuit type column. Ground nets get an ground icon.

Pull-up / pull-down resistors

Other issues in the interconnect verification are pull-up / pull-down circuits and IO standards which complicate verification. You want to make sure that there is only one pull-down (or pull-up) resistor on a signal line when a board is placed in the system.

BoardTrace analyzes the netlist and determines the power / ground signals and locates the pull-up and pull-down resistors. The resistors are shown in the netlist trace. The pull-up voltage (when determined) is shown between parenthesis.
