ODB++-File structure-Design Circuit
Board Electronic Pcb
When in use, ODB++ data is stored in a hierarchy of files and file folders. However, for transmission it is convenient to use common operating system commands that create a single, compressed file that preserves the hierarchy information. For example, on Unix
gzip commands can be used. In ODB++(X), the database is contained in a single XML file by default.
ODB++ covers the specification of not only conductor layer artwork and drill data, but also material stack up, netlist with test points, component bill of materials, component placement, fabrication data, and dimension data.
Valor was founded in 1992 and it released ODB in 1995. It added the ++ suffix when component names were added in 1997. The XML version was developed beginning 2000, and ended in 2008 with the donation to IPC. Valor was acquired by Mentor in 2010.
