Objective: To demonstrate that custom circuit on a chip that represent a Boolean function can be implemented using a gate array chip made of only NOR gates.

Description:

Gate array chips are widely used for putting custom circuits on a chip because most of the work $($depositing the gate array on the chip$)$ is independent of the circuit to be implemented. Only the wiring is specific to each design.

For this project, you will write a program that will simulate the behavior of an $mxn$ array of twoinput NOR gates. This circuit, contained on a chip, had $j$ input and $k$ output pins. The values of $j,k,m,$ and $n$ are compile$-$time parameters of the simulation.

Input: The program should start off by reading in a "wiring list" from a text file. Each wire should specify an input and an output. An input is either one of the $j$ input pins or the output of some NOR gate. An output is either one of the k output pins or an input to some NOR gate. Unused inputs are

Output: After reading in the wiring list, the program should print the output for each of the $2^j$ possible inputs.
