ODB++-Adoption-Custom Design Circuit
Board Electronic Pcb
In the late 1990s it became clear to industry participants that a second-generation data transfer format would be more efficient than the prevalent, first-generation Gerber format. However, it was very difficult to reach a consensus over which of two candidates should be selected:
ODB++: proven but proprietary
IPC-2511 GenCAM: not widely used but open
In 2002, a compromise format, ODB++(X), was recommended by National Electronics Manufacturing Initiative (NEMI; an industry body, subsequently renamed International Electronics Manufacturing Initiative, iNEMI) after a two-year mediation effort between the GenCAM and ODB++ camps. Companies that supported the recommendation at the time included Cadence, Hewlett-Packard, Lucent, Easylogix, Mentor (which acquired Valor some eight years later), Nokia and Xerox. But in fact adoption to date has been minimal. As a result, and as detailed below, the industry is still divided. Late 2014 Gerber X2 was introduced which added attributes ("intelligence") to the Gerber format in a compatible way, converting Gerber to a second generation format.
