AUTOTESTCON

September, 2008

• ATML = Automatic Test Markup Language

• Common Exchange Format for all Test and

Maintenance Information

• Developed by joint DoD – Industry Working

• Standardized by the IEEE

• In course of adoption by DoD services and

commercial companies

11.19.2008 ATML Demonstration 2

• Enable integrated multi-vendor COTS-based

solutions: Integrated Diagnostics, Enterprise

Health Management, etc.

• Support improvement of diagnostic accuracy,

reducing repair time and cost

• Facilitate ATE technology insertion and TPS

rehost

• Improve life cycle support of Weapon Systems

• Validate operation of ATML standards in system-level use cases

• Demonstrate feasibility of multi-vendor COTS-based solution

• Demonstrate integration on DoD (RTCASS-IP) and commercial (LM-STAR) platforms

• Provide feedback for DoD procurement and IEEE standardization

• Publish examples and guidelines for future users of ATML standards
