Abstract

Techniques to achieve greater diagnostic speeds using relatively small fault dictionaries, such as dictionaries that are only slightly larger than so-called N_FB dictionaries. This speed-up may be achieved by identifying a set of faults called hyperactive faults, and creating a dictionary for identifying those faults.

Claims

1. One or more computer readable media storing computer-executable instructions for causing a computer to perform any of the new and nonobvious methods or method acts described herein both alone and in combinations and subcombinations with one another.

2. A method of speeding up fault diagnosis comprising any of the new and nonobvious methods or method acts described herein both alone and in combinations and subcombinations with one another.

3. One or more computer readable media storing fault dictionaries generated at least in part by any of the new and nonobvious methods or method acts described herein both alone and in combinations and subcombinations with one another.

4. A diagnosis system that identifies one or more defects in integrated circuits using any of the new and nonobvious methods or method acts described herein both alone and in combinations and subcombinations with one another.

5. An integrated circuit diagnosed according to any of the new and nonobvious methods or method acts described herein both alone and in combinations and subcombinations with one another.

6. All new and nonobvious aspects of the disclosed technology performed as one or more method acts both alone and in combinations and subcombinations with one another or implemented as one or more computer-readable media storing computer-executable instructions for causing a computer to perform the method acts both alone and in combinations and subcombinations with one another.
