Revision as of 16:32, 28 September 2011
ODB++ is a CAD-to-CAM data exchange format[1] used in the design and manufacture of electronic devices to exchange printed circuit board design information between design and manufacturing, and between design tools from different EDA/ECAD vendors.[2] It was originally developed by Valor Computerized Systems, Ltd. (subsequently acquired by Mentor Graphics[3]) as the input database for their CAM system.[2] There are two versions of ODB++: the original (controlled by Mentor) and an XML version which is the result of collaboration between Mentor and the IPC organization[4] in an attempt to merge GenCAM (IPC-2511A/B) and ODB++. The XML version is called ODB++(X).[5] ODB stands for open database[6] with a ++ postfix evocative of C++.
File structure
When in use, ODB++ data is stored in a hierarchy of files and file folders. However, for transmission is convenient to use common operating system commands that create a single, compressed file that preserves the hierarchy information. For example, on Unix tar and gzip commands can be used.[2] In ODB++(X), the database is contained in a single XML file by default.[5]
Advocacy
Streamline Circuits claim that manufacturers are adopting it to overcome the limitations of the older Gerber format.[7] DownStream Technologies state that it is the defacto standard for intelligent data exchange in EDA.[8]
EDA tools that support ODB++
 | This article is missing information about section. (September 2011) |
EDA tools that support import and/or export of ODB++ include:[9][10] Advanced Design System and EMPro from Agilent's EEsof EDA division; Allegro and ORCAD from Cadence Design Systems; Expedition Enterprise, Board Station, and PADS from Mentor Graphics; CR-5000, CAD-Star, Board Designer, and Visula from Zuken; Protel and PCAD from Altium; various pre-processor and conversions tools from Artwork Conversion Software;[11] products by Frontline[12][13] (a joint venture of Orbotech and Mentor); and EDWinXP from Visionics.
Criticism and controversy
ODB++ is a proprietary format controlled by Valor and now Mentor. Mentor's fiduciary responsibility to its shareholders (and hence to compete against other vendors) is somewhat in conflict with its claim that it "...openly supports inclusion of ODB++ and updates for other EDA tool vendors. You are not required to use Mentor tools to take advantage of the benefits of ODB++."[14] Under pressure from the industry, the process of enhancing ODB++ and in particular ODB++(X) has become somewhat more open in recent years.[2]
