Inputs and Outputs

Before designing the 8-Bit Microprocessor, several components were designed. These includes

1. Inverter

2. Full Adder

3. NAND Gate

4. 1-Bit ALU

5. 8-Bit ALU

6. CPU

7. Controller

PAD Frame

The PAD frame of 900X900 was provided. The design was placed inside this frame and connections were made using metals 2 and 3. The empty spaces were then filled with poly. A GDS2 file was generated and sent for fabrication.
