//Example 16.2: An RTL gate has the worst case voltages listed below:
// Temp(degree C)            Voh(V)         Vih(V)        Vil(V)       Vol(V)
//     -55                   1.014           1.01         0.718        0.710
//      25                   0.844           0.815        0.565        0.300
//      125                  0.673           0.67         0.325        0.320
//Calculte the worst case NMl and NMh noise margins.
//Solution:
