Question

Develop a Verilog HDL design of the circuit provided. Show your HDL code as well as the simulation results.

The diagram illustrates a sequential circuit involving logical operations, flip-flops, and input values. Below is a detailed explanation of the components and their connections:

### Components:
1. **Inputs:**
   - There are two primary input signals labeled as **w** and **x**.

2. **Logic Gates:**
   - The circuit contains several logic gates, including AND and OR gates.
     - Each of the first two rows forms a pair of AND gates followed by an OR gate.

3. **Flip-Flops:**
   - Two D flip-flops are shown, labeled as **A** and **B**.
   - Each flip-flop has inputs **D** and **Clk** (clock), and outputs **Q** and **Q̅** (the inverse of Q).

4. **Output:**
   - The circuit produces an output labeled **F**.

### Explanation:
- The circuit begins with inputs **w** and **x** feeding into the logic gates.
- Each pair of AND gates takes a combination of inputs and possibly outputs from the flip-flops.
- The outputs of these AND gates feed into the OR gates, whose output connects to the D input of the flip-flops (A and B).
- The clock signal (Clk) synchronizes the flip-flops, facilitating the transition of stored values.
- Logic gates also receive outputs from the flip-flops to make subsequent calculations, forming a feedback loop characteristic of sequential circuits.
- Finally, another AND gate processes input signals and outputs of flip-flops to produce the final output **F**.

This configuration demonstrates a typical synchronous sequential circuit where outputs depend not only on current inputs but also on the system's state as maintained by the flip-flops.
