In this lab, you will be making a circuit that takes in two 4-bit words and adds them, yielding a 4bit output word. You will do this by starting small (with 1-bit operations) and synthesizing truth tables from word problems. Then, you will use Karnaugh Maps to simplify your 1-bit functions. Finally, you will build up the 4-bit circuit from the 1-bit "building blocks" through the methodology of "compartmentalized systems", using Hierarchical Blocks. Note: Always create a path name with NO spaces. Also, keep your files in the same place after saving. Otherwise, path references in the hierarchical blocks will get messed up. I recommend navigating to your OneDrive and creating a new folder for saving your designs and circuits before you start. Part 1: In Multisim, create a simple 1-bit adding circuit. This circuit should sum the inputs A and B, plus the input carry bit C to produce the output S. For now, assume there is no carry out of the circuit, and generate a truth table which describes the logic for an adder circuit using A, B, Cin, and S. (Hint: S will be zero when sum =0 and when sum =2.) Work backwards from a truth table and Karnaugh map to create a positive logic schematic based on the sum-of-products expression. Once a schematic is created, use the Multisim logic converter to verify that the circuit operates as expected. Save this design as adder_1bit in your desired OneDrive folder; this is the folder that all your Hierarchical Blocks will be saved in. In your report include schematic and results from logic converter
