Electrical Rule Checks
Missing Footprints
Reports parts that have no footprint.
Design Rule Checks
Overlapping Copper
Reports copper elements that are shorting.
Invalid Layer
Reports nodes that are assigned to a layer that doesn't exist in the layout stackup.

Designator | Ruleset | |
|---|---|---|
Airwires
Reports missing routed traces between pads in a net.
Deprecated Rules
Reports nodes that are using rules that are not supported anymore.
Layers with Multiple Fills
Reports layers that have multiple copper fills of different nets. Make sure the Connected Layers rule value of nets with fills is valid.
Floating Copper
Detect any via, trace or copper fill island that is not connected to any net.
Protected Intrusions
Reports intrusions from objects of other nets into polygons or fills that have the Protected layout rule applied.
Manufacturing
Manufacturer Part Number
Reports parts that have no manufacturer part number.
Parts Available
BetaChecks that all parts have a part number and are available from distributors.
System Checks
Auto-Layout
BetaReports issues with Auto-Layout if Flux cannot route something or must ignore a configuration.
Passive Components
Resistor Power Rating
BetaChecks that the power traveling across a given resistor is under its rating with 50% headroom.
Learn morePull Up/Pull Down Presence
BetaChecks that IC pins that require pull up or pull down resistors have them.
Learn moreCapacitor Voltage Rating
BetaChecks that capacitors have appropriate voltage ratings to prevent overheating and ensure reliable circuit operation.
