Using Component Libraries >
Component Definition Overview >
   Parameter Data and Dependent Data       

Parameter Data and Dependent Data

The information stored in a component includes both parameter data and dependent data.

• Parameter data describes the internal electrical characteristics of the component, and is stored with the component definition in the component library .aclb file.

• Dependent data describes associated physical characteristics — such as symbol, footprint or padstack definitions — and is contained in an external library file referenced by the component definition.

The following external library files are available in Designer.

Materials

Material information defines the physical properties of a substance — such as substrate, metallization, or solder mask layer — for its inclusion in a stackup, the physical foundation of a manufacturable layout or Planar EM model. Material definitions are stored in library files with the extension .amat. See Using the Material Editor for how to create and modify materials.

Scripts

The Designer Script Editor supports the viewing, modification, and saving of script file information for footprint elements and graphical primitives. After modifying a script, the information can either be saved, used to render a footprint, or exported. Script definitions are stored in library files with an extension of .dsc. See Using the Script Editor for how to create and modify scripts.

Components

The Designer Component Editor supports the viewing, modification, and saving of information for component elements and graphical primitives. After modifying a component, the information can either be saved, used to render a component, or exported. Component definitions are stored in library files with an extension of .asty. See Using the Component Editor for how to create and modify components.

Padstacks

A padstack defines the physical structure and electrical connectivity of a pad, the region in which a component pin connects to a copper trace. A padstack must be associated with each pin of a component. Padstack definitions are stored in library files with an extension of .pslb. See Using the Padstack Editor for how to create and modify padstacks.

Symbols

A symbol is graphical representation of a component in a schematic. Symbol definitions are stored in library files with the extension .aslb. See Using the Symbol Editor for how to create and modify symbols.

Footprints

A footprint defines the planar space consumption, physical orientation, metal usage, and electrical connectivity of a component in a layout. Footprint definitions are stored in library files with the extension .aflb. See Using the Footprint Editor for how to create and modify footprints.

Models

The Designer Model Editor supports the viewing, modification, and saving of information for C Model elements. After modifying a C Model, the information can either be saved or exported. Model definitions are stored in library files with an extension of .lib. See Using the C Model Editor for how to create and modify C Models.
