Page1 Framework Working Group 2007 ATML Use cases Use of ATML by external agencies is gathering momentum

Page2 Framework Working Group 2007 Agilent Instrument Database Performing an independent evaluation into using the ATML instrument description and ATML capability to distribute their instrument information. This is important because, if successful, there will be a lot of information in the ATML format – that will generate a lot of user based feed back on our trial use standard(s) Dan Pleasants presentation Instrument Description Working Group Meeting Tuesday Morning 9:00

Page3 Framework Working Group 2007 Synthetic Instrument defined using ATML Synthetic Instrument Working Group has defined a general architecture for synthetic instruments. Each component that makes up the synthetic instrument needs both software and hardware interchangability. ATML Instrument Description has been chosen as the format to represent the description of the hardware specifications for the following components: Arbitrary Waveform Generator Digitizer Down Converter Up Converter IVI Drivers have been selected for the software driver interchange format.

Page4 Framework Working Group 2007 LXI Consortium Investigating using ATML Capabilities as part of LXI Discovery

Page5 Framework Working Group 2007 MoD Open System Architecture Approach The MoD currently have a policy for ATS to use the IEEE 1641 signal modelling standard. Looking to standardise a common Open System Architecture approach This process is expected to make heavy use of the ATML standards

Page6 Framework Working Group 2007 Proposed Common OSA Standards High degree of obsolescence coupled with a lack of commonality has resulted in: High in-service support costs Relatively low utilisation of test platforms A common open standard is therefore vital to overcome these concerns. This must be encompassed within the common GPATE with the technology to achieve this capability.

Page12 Framework Working Group 2007 REQUIRED Common Use Standard Signal Library TSF Development We need to develop standard Signal libraries to capture the test domain knowledge of what signals are required. CASS ATLAS Signal Library Already modelled certain signals and measurements in 1641 (but never completed as TSFs) SIWG measurement science & signals methods ARGCS ATLAS Signal Libraries Train users in using the common signal libraries in their field of operation rather than the user needing to know how specific signal are implemented. TPS projects and field test engineers would then use these TSF signal definitions as reusable components, rather than continually build there own up from scratch Provide a solid foundation for a standard common use signal library Ability to use additional interchangeable Signal Libraries though TSFs New TSFs can be added into the standard at subsequent revisions

Page23 Framework Working Group 2007 Signal Modelling and the Framework The term signal modeling is simply defining signals through models. A signal model includes signal sources, signal conditioning, signal based measurement, digital, communications & busses, events, timing and even locations or combination of them. The model is an executable specification that provide a means to define both behavior and interface parameters, and utilize both composition and hierarchy to allow building increasingly complex signal definitions, as reusable components Regardless of the complexity of the signal, because they define behavior, signal models represent an ideal component of test requirement interchange. Signal modeling can have a positive impact on several DoD (and MoD) objectives Improve instrument Interchange Make ATE more adaptable with no penalty to requirements Faster technology insertion Improve TPS rehost Improve TPS interoperability Use model based programming techniques Modernize test programming environment Capture design to test data
