ECE 411 – Electronic Design Automation http://angel.msu.edu/ Instructor: Prof. N IHAR R. M AHAPATRA Solutions to Homework 1 Note: Grading scheme used is given at the end. Problem 1.3 [10 points] 00 01 11 10 00 × G + H 01 × E E × 11 1 F 1 10 F CD AB We note that since < ABCD > = <0100>, <0001> and <1001> are disallowed, they are “don’t cares.” From the map, E = F ’ = G + H ’ = 0 gives MS 0 = B D . Then, E = 1, F ’ = G + H ’ = 0 gives MS 1 = C D . Next, F ’ = 1, E = G + H ’ = 0 gives MS 2 = ABC . Finally, G + H ’= 1, E = F = 0 gives MS 3 = BC D ’. Therefore, Z = B D + C DE + ABCF ’ + BC D ’( G + H ’) = B D + C DE + ABCF ’ + BC D G + BC D H
