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++.".<ref>{{cite web |

ODB++ is a data format used in the design and manufacture of electronic devices to exchange printed circuit board data between design and manufacturing, and between design tools from different EDA vendors.[1] It was originally developed by Valor Computerized Systems, Ltd. (subsequently acquired by Mentor Graphics[2]) as the database for their CAM system.[1] 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[3] in an attempt to merge GenCAM (IPC-2511A/B) and ODB++. The XML version is called ODB++(X).[4]
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.[1] In ODB++(X), the database is contained in a single XML file by default.[4]
