        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.
    - Results
    - Lock Security Setup
      DFE input rule file (*.SDFEI) can be locked to prevent any modifications from users.
  - Technical Cleanliness
    PollEx Technical Cleanliness (TC) is an optional module of the PollEx PCB and a reliability analysis tool set for hazardous areas on a PCB design, using its micro particles.
