Layers
When working with EDA files, AutoVue lets you view all the physical layers and associated logical layers of the EDA drawing; you can view all layer sets for that file, or create your own. Additionally, you can manipulate certain layer attributes, such as visibility, color, and ordering. The layer settings are accessed via the Layers option.
Note: For drawings which do not contain layers, the Layers menu option and button are disabled.
From the Manipulate menu, select Visibility Control, and then select Layers.
The Layers dialog box appears.
Note: From the AutoVue toolbar, you can also click Layers
.
The Layers dialog box has a Physical Layers section and a Logical Layers section. You can display and hide these sections by clicking Expand
and Collapse
, respectively.
Physical and Logical Layers Sections
The Logical Layers section displays the layers in the order they display in the workspace. The Physical Layers section displays the layers in the order they appear in the layer stackup when manufactured.
The Physical Layers section displays a matrix with a mapping of physical layer names to entity types. Each row in the matrix corresponds to a physical layer in the board. Each column in the matrix lets you control the visibility of an entity type, such as pin, via, or trace. The entity types that display depend on the entities available in the open file. Select a physical layer to change its visibility, layer order, and color. Select or deselect the entity type of a physical layer to affect its visibility separately from the other entities of the layer.
When you select a physical layer from the Physical Layers section, the associated logical layers are also selected in the Logical Layers section. You can also select individual logical layers from the Logical Layers section, or press the Shift or Control key to select multiple logical layers.
Note: One physical layer can be selected at a time.
The Logical Layers section displays a list of logical layers and the layer attribute options you can modify: visibility, order, and color.
To modify these attributes for both physical and logical layers, first select the layers you want to modify, then use the settings to make the changes you want.
When you select physical or logical layers and modify settings from the Layers dialog box, a message displays at the bottom of the dialog box to indicate your last action.
When you are satisfied with the changes, click Apply to make the changes in the workspace. You can also create layer sets to save your modified layer settings to reuse them later.
When you open a file, it displays all layer sets for that file. You can choose the layer set you need, or create your own.
