This removes the burden on librarians to record all changes made to a part. [. . . ] Users can copy pin-out/ball-map diagrams from datasheets into Allegro PCB Librarian XL. The data is automatically interpreted and can be fine-tuned to meet company naming standards. Additionally, users can copy complete tables of information from datasheets with configurable translation of pin types and bus notations. Figure 4: Preview window for viewing and editing part data before importing · MentorGraphicsDesignArchitect · AllegroPackageDesigner · FPGA(Xilinx, Actel, Altera) · IBIS · DML Die file import enables co-design while FPgA import helps in implementing FPgA flows in front-end design. With iBiS and DML model import, front-end models can be easily created from third-party highspeed models. User-configurable data translation rules make it easy to customize data import. These rules manipulate part, pin, and property names as well as other part details. SCHeMATiC SYMBol eDiTing Allegro PCB Librarian XL comes with a powerful graphics editor for creating reusable shapes and schematic symbols. An editable spreadsheet with symbol information and a symbol editing canvas with expert features, such as separate grid controls for pins and non-pin objects, give users the flexibility to do bulk operations and intricate graphics work according to their needs. Automatic symbol generation based on user preferences makes it easy to create large­pin-count devices--devices that DATA iMPorT Allegro PCB Librarian XL provides a variety of import options and utilities to accelerate part creation. Users can create schematic parts by importing part data in formats such as: · EDAXML · Si2PinPakXML · VHDL · Verilog · SynopsysPTMmodels · CSVandtextfiles · Dietext · Pingrids · Pintables · CadenceOrCADCapture · MentorGraphicsViewdraw Pinout description in PDF Imported data after mining Created and validated part Figure 5: Import of part data in pin-grid format from PDF www. ca de nce . com ALLEg ro PCB Li BrAri A n XL 3 might have thousands of pins distributed among dozens of symbols. A simple pin distribution interface makes it easy to move pins between symbols to meet engineering requirements. The spreadsheet editor for part information speeds many part development operations, including: · Convertingscalarpinstovectorpins and vice-versa · Expandingandcollapsingvectorpins · Switchingbetweenvisibleandinvisible power pins · Filteringandhidingoperations · Findingandreplacing A comparison Ui makes it easy to compare interfaces of various part entities including footprints, schematic symbols, and Si models. The ECo import mode makes implementing incremental changes remarkably easy. This mode retains original data, while allowing new, possibly conflicting data to be imported. The data can then be compared and resolved to produce parts. The ECo mode greatly reduces rework in cases where input data changes frequently. The ECo preview window allows users to view and evaluate newly imported data before committing to the change. VAliDATion Allegro PCB Librarian XL 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 reduces costly design iterations by ensuring that a part is correct from the start. Allegro DeSign WorKBenCH inTegrATion Allegro PCB Librarian XL is an integral part of Allegro Design Workbench. When combined, these technologies comprise the most powerful board-level library and design data management system available 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. [. . . ]
