The testability structure for digital circuits described in IEEE Std 1149.1-1990 has been extended to provide similar facilities for mixed-signal circuits. The architecture is described, together with the means of control of and access to both analog and digital test data. Sample implementation and application details (which are not part of the standard) are included for illustration.

Other Activities From This Working Group
Current projects that have been authorized by the IEEE SA Standards Board to develop a standard.
P1149.4
IEEE Draft Standard for a Mixed-Signal Test Bus
The testability structure for digital circuits described in IEEE Std 1149.1™ has been extended to provide similar facilities for mixed-signal circuits. The architecture is described, together with the means of control of and access to, both analog and digital test data. Sample implementation and application details (which are not part of the standard) are included for illustration. Also, extensions to the standard Boundary-Scan Description Language (BSDL) are defined that allow description of key component-specific aspects of such testability features.
Standards approved by the IEEE SA Standards Board that are within the 10-year lifecycle.
No Active Standards
These standards have been replaced with a revised version of the standard, or by a compilation of the original active standard and all its existing amendments, corrigenda, and errata.
No Superseded Standards
These standards have been removed from active status through a ballot where the standard is made inactive as a consensus decision of a balloting group.
No Inactive-Withdrawn Standards
These standards are removed from active status through an administrative process for standards that have not undergone a revision process within 10 years.
1149.4-2010
IEEE Standard for a Mixed-Signal Test Bus
The testability structure for digital circuits described in IEEE Std 1149.1-2001 has been extended to provide similar facilities for mixed-signal circuits. The architecture is described, together with the means of control of and access to, both analog and digital test data. Sample implementation and application details (which are not part of the standard) are included for illustration. Also, extensions to the standard BSDL are defined that allow description of key component-specific aspects of such testability features.
