Question
**Title:** Designing a 4-Bit Adder Using CMOS

**Problem Statement:**
A circuit designer developed the layout below to design a 4-bit adder.

**Tasks:**
A) Provide the Boolean function of the layout.
B) Draw a CMOS schematic using Electric and take a snapshot of it.

**Layout Description:**
- **Visual Components:**
  - The layout includes regions labeled as PMOS and NMOS transistors, which are fundamental components of CMOS technology.
  - The topmost horizontal line is marked as VDD (power supply), and the bottom is GND (ground).
  - Inputs are labeled as C0, P0, and G0, located on the left side of the layout.
  - There is an output label, F, represented at the right side.

- **Color Coding and Connectivity:**
  - **Red and Blue Lines:** Indicate the connections between the transistors, possibly representing metal or polysilicon lines for connectivity.
  - **Green Rectangles:** Mark the locations of the PMOS and NMOS transistors, separating different stages of computation.
  - The pink-colored paths intersecting the transistors show possible polysilicon gate connections.

This layout is a visual representation used to generate a 4-bit adder circuit on a CMOS platform. The task requires interpreting this layout to form a Boolean function and use design software like Electric to create a CMOS schematic representation.
