Hello, I think many of you miss the point of having ODB++ export. It's not really usefull for PCB manufacturer, you can always go with gerber + IPC netlist. But for simulation software you usually need a CAD file (mentor/cadence/...) or an ODB++ with Net and components definition. The copper/net part of the ODB++ can be easily be generated with CAM software from gerber and IPC netlist. The missing part is the component definition.It's also usefull for documenting PCB by using integrated software like Blueprint(tm)(c)
I'm currently working on a python script that generates the component definition
and add it to the file tree generated by CAM software. Le 12/09/2015 22:06, Lorenzo Marcantonio a écrit :

Do PCB manufacturers support it?IPC specs are usually open as in 'buy the paper and then you can implement it'; no consortium, no mandatory fee/royalties/whatever. As in manufacturers support, my experience is that manufacturers just supports gerbers/excellon and maybe one or two CAD packages they have available (usually OrCAD and/or PADS); OTOH since it seems that *all* of them are using genesis 2000 (at least here in italy), they could support OBD++ (but maybe that's an additional license in genesis to buy!)
