The University of Alabama in Huntsville Electrical and Computer Engineering CPE/EE 422/522 Spring 2005 Homework #7 Solution From the book, 10.1 (20 points) (a) & (b) for q s-a-0 and d s-a-1 (a) Determine the necessary inputs to the following network to test for q s-a-0 and d s-a-1. (b) For this set of inputs, determine which other stuck-at faults can be tested. q s-a-0 ABCD = 1000 detects q s-a-0 and also detects c s-a-1, d s-a-1, r s-a-0, t s-a-1, v s-a-0, and F s-a-0 ABCD = 1100 detects q s-a-0 and also detects a s-a-0, r s-a-0, t s-a-1, v s-a-0, and F s-a-0 d s-a-1 ABCD = 1000 detects d s-a-1 and also detects q s-a-0, c s-a-1, r s-a-0, t s-a-1, v s-a-0, and F s - a - 0 ABCD = 0000 detects d s-a-1 and also detects c s-a-1, p s-a-1, q s-a-0, r s-a-0, s s-a-0, and t s-a-1 ABCD = 0100 detects d s-a-1 and also detects a s-a-1, c s-a-1, p s-a-0, r s-a-1, t s-a-1, u s-a-1, v s-a-1, and F s-a-0 10.2 (20 points) Find a minimum set of tests that will test all single stuck-at-0 and stuck-at-1 faults in the following network. For each test, specify which faults are tested for s-a-1 and s-a-1. abcdefi = 0001001 a s-a-1, b s-a-1, c s-a-1, g s-a-1 abcdefi = 1000001 d s-a-1, e s-a-1, f s-a-1, h s-a-1 abcdefi = 1001001 g s-a-0, h s-a-0, i s-a-0, Z s-a-0 abcdefi = 0101001 b s-a-0 abcdefi = 0011001 c s-a-0
