Circuit from state diagram X76378

Design a sequential circuit described by the following state diagram.

The circuit has two inputs (x₁,x₀) and one output (z). The inputs can take the values 00, 01 and 10 (the value 11 will never occur and can be considered as a don’t care).

Specification

module state_machine(x, z, clk, rst); input [1:0] x; input clk, rst; output z;

Input

• clk is the clock signal.
• rst is the synchronous reset signal.
• x are the two input signals.

Output

• z is the ouput signal.
