RICK: A DFT advisor for digital circuit design

摘要

Design for testability (DFT) requires digital circuit designers to address the issues of testability during the design phase. To simplify this task, a number of knowledge-based DFT expert systems have been suggested. A DFT advisor which can offer testability advice to the designer at all the stages of the design phase is described. It is implemented using the constraint programming language Galileo.
