WebATPG Algorithms. Since combinational fault simulation is O(n2), RPG and fault simulation is much more efficient. This is the driver for using RPG followed by ATPG for the hard-to … 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.
