A powerful wizard enables users to quickly create footprints using templates that handle most package types—including DIP, SOIC, PLCC/QFP, PGA/BGA through- hole discrete, SMD discrete, SIP, and ZIP. The pad designer facilitates the creation of any shape pad and padstack. It allows users to define the pads for each layer in the stack-up as well as various mask layers, hole types, and slots. Validation Allegro PCB Librarian provides extensive part validation capabilities with built-in checks at every stage of the part creation process. For imported data, validation occurs at the time of import. When data is entered in the part editor, it is checked in real time for valid characters, lengths, permitted values, and syntax. Symbol- package checks guarantee that parts will work in the complete PCB design flow. Footprint validation routines allow users to compare pin numbers specified at the time of schematic symbol development with PCB footprints. This online check ensures that schematic components and footprints are in sync. Most verification is done in real time without leaving the editor. Additionally, batch validation provides automated design flow verification that significantly reduces the burden on librarians. Users can run detailed packaging checks that instantiate the schematic symbol in a schematic sheet, create a netlist, and place the footprint into a layout file or quick checks that help them determine, in considerably less time, if a part can be packaged. User-defined symbol and footprint checks can be built for schematic parts and footprints. These can operate on one part at a time or on complete libraries. Comprehensive rule development and checking guidelines are provided both for schematic symbols and PCB footprints. Consistency checks are done whenever a part is saved or loaded for editing. Part error status is stored with the part and displayed whenever the part is opened or closed. Allegro PCB Librarian provides a standard rule set and a developer's toolkit for building user-defined rules. Using these rule sets and the built-in part valida- tion system, librarians can push parts through the advanced rule checking and advisement system. This reduces costly design iterations by ensuring that a part is correct from the start. Allegro Design Workbench Integration Allegro PCB Librarian is an integral part of Allegro Design Workbench. When combined, these technologies comprise the most powerful board-level library and design data management system avail- able today. It allows users to manage and distribute their Allegro schematic and PCB libraries. Component information can be included from datasheets, ERP, MRP, or other sources. By setting up a standardized part develop- ment flow across their organization, users can reduce errors and accelerate library development. This approach significantly increases productivity and improves the quality of their library. Configurable flow management capabilities allow users to manage their library development process and tailor it to their specific needs.
