Bit Accumulator Design and Simulation with OrCAD PSpice Ck CE D Ck CE D Ck CE D Ck CE D Sn S3 S, 1-bit Full Adder C1-bit 1-bit Full Adder C2-bit1 Full Adder Full Adder Ya ys Y2 Fig. 1 a 4-bit Accumulator with addition function only Task 1: Design a 4-bit accumulator with addition and subtraction functions at gate level. Create an OrCAD Capture schematic for your design. Note: only AND,NAND INV.OR or NOR gates are allowed in the design, Task 2: Test and simulate the circuit in Task 1, by using PSpice A/D. Verify the functionalities of the accumulator. The accumulator start value should be "0000". Material for submission: 1. 2 pages of typed report to describe your design and observations 2. Capture schematic printouts 3. Stimulus signals printouts Note: Grades will be based on simplicity of the design, and simulation results. Please show detailed design steps. 4-Bit Accumulator Design and Simulation with Or CAD P Spice: Please help with Task #1 by providing detailed design steps.
