Combinational Logic

Load the PSPICE file comb1.sch.

Simulate the circuit and note the logic levels marked on the schematic screen. Change the input values and simulate again, an check some entries for the truth table for the function.

To display the logic values on the schematic screen, make sure that transient analysis has been enabled before you simulate.

To change input values, delete and add the HI and LO parts (you can't change parameters).

Create a new schematic for the logic function

$$f(A,B,C) = AB + \overline{B}C + \overline{A}BC$$

after you have minimized it. Simulate and verify correctness of your circuit.
