Web• The ATPG_untestable fault class includes all faults for which the test generator is unable to find a pattern to create a test, and yet cannot prove the fault redundant. • Testable faults become ATPG_untestable faults because of constraints, or limitations, placed on the ATPG tool (such as a pin constraint or an insufficient sequential depth). WebThis learning path will introduce you to scan and ATPG processes. You will gain knowledge on fault models, test pattern types and at-speed testing. 12 month subscription.

I found this hierarchy fascinating, as it offers new insight about faults and tests covering them.

Webf fault line sensitized to f Primary Inputs Primary Outputs Sometimes a fault f on line l cannot be excited or cannot be propagated or both. Then the fault f is termed untestable. If the fault f is untestable, then the fault f is redundant, i.e., the line l or the associated gate can be removed from the circuit without changing the logic function. http://tiger.ee.nctu.edu.tw/course/Testing2024Fall/notes/pdf/lab2_2024F.pdf
