        Connected Pins
        This rule checks whether specific components are connected.
        Exist Comp
        This rule checks whether specific components are connected to specific net and check its count.
        NC Pin
        The NC Pin DFE rule checks for the NC pin connectivity.
        Pair Comp
        This rule checks whether two specific components are connected.
        Polarity
        This rule checks for the connectivity of components that have polarities.
        Prefix
        This rule checks whether specific component use specific name string as a reference name.
        Prohibited Duplicated Net
        This rule checks if duplicated net name is used in same component.
        Prohibited Component
        This rule checks if duplicated net name is used in same component.
        Standard Net Name
        This rule checks whether the nets connected to specific component have standard net name.
        Duplicated Pins
        The output pins of power device can be connected to the same net to flow large current. This rule checks whether the out pins of same device are connected to the same net. And check if the output pin of target device is connected to the specified net.
        Input Threshold Voltage
        This rule navigates the power and signal nets to find the voltage, then checks if the signal voltage for the input pin is between Vil_max ~ Vih_min. It also checks that the input power voltage for the power pin does not exceed the allowable value.
      - Stress Test
        Manage and define stress test rule checks.

Pair Comp

This rule checks whether two specific components are connected.

There are occasions that components should be connected to certain signals and placed together with other components.

A transient load decoupling capacitor should be placed close to the device requiring the decoupled signal.
A power supply decoupling bypass capacitor should be placed close to the voltage/current source.
Placing a ferrite-bead close to the noise generating component pin helps reducing EMI.

Item: Input item name.
Comp1: Select 1st component group.
Comp2: Select 2nd component group which should be exist with comp1.
Net Group: Define component group that two components should be connected.
