The Layout Editor shows the physical realization of a circuit. Layers are used in the editor to organize and manipulate sets of geometry and other visual indicators.
- Signal, negative signal, and dielectric are common physical layers.
- Symbol, error, and rats are non-physical layers.
The Edit Layers window stackup contains additional properties of the physical layers, such as material, thickness, and elevation. Geometrical information on these layers is used to generate masks for manufacturing.
