PAR Proposal:IEEE-P1505.2 Portable-Bench Top Universal Pin Map
Proposition… • 5.4 Purpose of Proposed Standard: To provide a standardized portable-bench top I/O pin map to enable the interoperability of compliant interface fixtures (also known as interface test adapters, interface devices, or interconnection devices) on multiple ATE systems. utilizing IEEE 1505 Receiver-Fixture Interface (RFI) framework in scalable universal configurations. • 5.5 Need for the Project: There is no current standard (formal or defacto) standard that defines a scalable universal pin map for portable and bench top test systems utilizing IEEE-1505. The universal approach is required to support greater pin independence and versatility in how we interface test system resources to the Unit-Under-Test (UUT). Users of ATE Systems also need for greater transparency in migrating test program set software and adapter/fixture hardware between test systems. This project will mitigate these difficulties by applying a scalable universal pin map specification, which will permit the pin map to be extended and/or reconfigured through means of automated software driven test system tools. This project will serve to realign differing wiring points into a functional signal path relationship. • 5.6 Stakeholders for the Standard: Primary stakeholders are commercial, military and aerospace owners of portable and bench top ATE Systems.
Current solutions: a. Primarily represents commercial test interfaces with random connectors and configurations, that are typically dedicated to custom design and applications having discrete signal performance, or where test interfaces are supplied. b. Typical test I/O interfaces have no established standards beyond low-end connector/contact level, nor do they easily migrate or interoperate between testers. Review of Existing Options…
