Can I ask my layout house who is using Cadence Allegro to output ODB++ file?
Is fab house love to have this format?

Hi Ken!

A paste from Valor's web page is below, and there's a *.PDF document about
OBD++ at:

http://www.valor.com/obd.pdf

-Steve Gregory-

"ODB++ is the most intelligent CAD/CAM format available today, capturing all
CAD/EDA, assembly and PCB fabrication knowledge in one single, unified
database. Originally developed by Valor Computerized Systems for use in its
own PCB CAD/CAM systems, Genesis 2000, Enterprise 3000 and Trilogy 5000,
ODB++ is quickly taking its rightful place as the de facto industry
standard,
providing unprecedented power to PCB design, fabrication and assembly, with
the flexibility to expand as required.

Unique, Expandable Structure

ODB++ is an ASCII open format which captures a vast knowledge base gleaned
from the PCB design, fabrication and assembly arenas. Some formats, such as
Gerber and Excellon, are too simplistic and ambiguous by nature. Other
proposed standards have an implicit, CAD-like structure which may lead to
misinterpretation of data. But ODB++ combines an explicit structure with an
unprecedented level of intelligence to describe the actual board.

Features

Analysis results included inside Checklists assure easy viewing by all
parties, as well as verification of checks run and criteria used.

Includes a wide range of system attributes such as impedance,
plated/non-plated holes, layers connected by specific holes, etc.
WYSIWYG description of layers eliminates ambiguities.
Notes can be attached to x-y locations and specific layers.
Attributes at the single feature level.
Unique board layer and order definitions.
Support for data placed in panel layers.
Exact area for each pin included inside the component.
Supports merging of BOM data
Installed and in use at over 500 Sites
Outputs already exist from Open Systems Alliance partners, Cadence, Mentor
Graphics, PADS, VeriBest and Zuken-Redac.
