Allegro Front-to-Back User Guide Creating and Managing Libraries October 2019 18 Product Version 17.4-2019 © 1999-2019 All Rights Reserved. Creating and Managing Libraries The Design Entry HDL libraries are maintained using the PCB Librarian toolkit. Along with other tools, this toolkit comprises: ■ Library Explorer—Lets you create and maintain libraries. Using the familiar Windows NT Explorer interface, you can manage library build areas and launch applications to edit parts and views in a library. ■ Part Developer—Lets you create and edit schematic symbols, package information (chips), and physical part tables. You can also create parts from XML files and create Verilog and VHDL wrappers/map files. ■ Part Table Editor—Lets you create and maintain Part Table files. Library Explorer The Library Explorer tool lets you create, view, and maintain part libraries. You can use Library Explorer to: ■ Create and maintain build areas ■ Browse reference libraries ■ Import and export files, parts, and libraries to and from the build area ■ Create new libraries and cells You can create new libraries within the build area and new cells under the library. You can then edit the cells using Part Developer. ■ Create and maintain library category files ■ Launch Part Developer and other tools to create and edit library parts You can select a part or view and launch Part Developer to edit that part. You can also launch Design Entry HDL for editing or viewing symbols, or use the Open function to display a file in the text editor of your choice. For more information about creating libraries, refer to Library Explorer User Guide. Part Developer Part Developer is a tool for creating, editing, and verifying part data. It can be launched from Library Explorer once the user has selected an existing part or named a new part. It lets you edit the schematic symbol, physical pin data, and part table data and create simulation views
