use multi-sheet diagrams in a few ways: Simple hierarchies (each schematic is used only once). Complex hierarchies (some schematics are used more than once with multiple instances). Flat hierarchies currently doesn’t treat this second case. A hierarchy can be: simple: a given sheet is used only once complex: a given sheet is used more than once (multiples instances) flat: which is a simple hierarchy, but are seen as connected between them across all the hierarchy. Note Within a hierarchy (simple or complex) one can use both hierarchical labels and/or global labels. 7.4. Summary of hierarchy creation

other elements can have snapping points depending upon the settings in the user preferences. In complex designs, snap points can be so close together that it makes the current tool action difficult. Both smoothing, and a value of 3 will result in the finest smoothing. Higher values will result in longer processing time and larger Gerber files. Smoothing amount is a ratio that controls the size of the smoothing design constraint rules apply to selected items. These tools can help when designing PCBs with complex design rules where it is not always clear which rules apply to an object. 45 To inspect the clearance

explicitly connected in a master diagram). Simple hierarchies (each schematic sheet is used only once). Complex hierarchies (some schematic sheets are used multiple times). Hierarchical schematics are described Hierarchical designs can be put into one of several categories: Simple: each sheet is used only once. Complex: some sheets are instantiated multiple times. Flat: a sub-case of a simple hierarchy, without connections root sheet. Two of the subsheet symbols are shown below. 35 Complex Hierarchy The complex_hierarchy demo project is an example of a complex hierarchy. The root sheet contains two subsheet symbols, which
