The goal is to create an 8-bit register from scratch, using only the three basic logic gates (inverting inputs of AND, OR gates is allowed, since this simply adds a NOT gates in front of the respective input; also a NOR gates (OR and NOT gate chained together) are okay to use). All necessary labels are given in the Important section below. 1. Create a subcircuit called "SR Latch" and add the circuit for the SR latch. 2. Create a subcircuit called "Level-Sensitive SR Latch". Add "SR Latch" as subcir- cuit (s) and the required circuit around it to create a level-sensitive SR latch. 3. Create a subcircuit called "D Latch". Add "Level-Sensitive SR Latch" as subcir- cuit(s) and the required circuit around it to create a D latch. 4. Create a subcircuit called "D Flip Flop". Add "D Latch" as subcircuit(s) and the required circuit around it to create a D flip flop. 5. Create a subcircuit called "4-Bit Register". Add "D Flip Flop" as subcircuit(s) and the required circuit around it to create an 4-bit register. Use one 4-bit input and one 4-bit output. You will have to use splitters to connect everything to the input/output. 6. Create a subcircuit called "8-Bit Register". Add two "4-bit Register" as subcir- cuit(s) and the required circuit around it to create an 8-bit register. Use one 8-bit input and one 8-bit output. You will have to use splitters to connect everything to the input/output.
