a) What is the maximum possible die size in mm^2 if the marketing group says the die cost must be no more than $14 per chip?
b) Chip designers who did not take EEC 116 design the chip 3x larger than the size calculated in part (a). What is the new cost of the chip?
Using the magic "getcell" command, place 8 copies of the full adder cell into a new cell called add8, paint small extensions onto each input, output, Vdd, and Gnd node, and place new labels with the names a0-a7, b0-b7, sum0-sum7, cin0, cout7 (25 pts).
Simulate the add8 cell in irsim in one simulation with the following input combinations and clearly show the inputs and correct outputs sum and cout7 in an irsim output listing or waveform (40 pts). State how many tests are correct (10 pts).
a = 00000000, b = 00000000, cin0 = 0 a = 00000000, b = 00000000, cin0 = 1 a = 00000001, b = 00000001, cin0 = 1 a = 00000101, b = 00001011, cin0 = 0 a = 00000001, b = 00111111, cin0 = 0 a = 11111111, b = 00000001, cin0 = 0
