Abstract
This research applies elements of current monitoring methodologies to both analog and mixed signal automotive integrated circuit designs and discusses implementation, data analysis and future uses.
The problem is drive for continuous improvement for both capability and efficiency in the areas of defect detection for integrated circuits, specifically automotive. Integrated circuit designs not optimized for error detection in testing may employ only parametric and functional testing because of their testability limitations, particularly Iddq. The methods applied in this research examine these limitations and present treatment of data along with considerations for implementation. Realizations of current monitoring include both an application to a digital implementation of an analog function and an application of an Iddq pattern to an automotive mixed signal integrated circuit design with combined power domains. Through monitoring currents rather than using steady state measurements within ATE (Automated Test Equipment) programs, considerations for implementing cur- rent monitoring and data collection are discussed and results are analyzed within the two distinct studies.
In summary, development and results of applying current monitoring and Iddq techniques to analog and mixed signal automotive integrated circuit designs within a specified taxonomy are examined. Treatment and analysis of data is presented which resulted in successful defect detection of Iddq-only failures in a combined power domain integrated circuit design.
