This correspondence indicates a weakness in forming the criteria used to decide when random testing is practical. The use of average fan-in based on total gate count is an oversimplification and results in too low a threshold for use of random testing in lieu of a complete test of 2N patterns. A modification is given to avoid this difficulty.
