Design a 4bit updown counter using D flipflops The up or dow

Design a 4-bit up-down counter using D flip-flops. The up or down count is decided by the logic value of a direction input, U. If U=1, the counter will count up. If U=0, the counter will count down.

Also, verify your design’s functionality with Multisim

You should turn in a report on TITANium before the deadline. The report should contain the following:

1. A Problem statement or Objective statement

2. A Methods and procedure section. In this section, you need to discuss your design approach. You should also include the present-state and next-state tables, the table for flip-flop inputs, and the simplification procedure, as applicable. You many choose to do either minimum SOP or minimum POS simplification.

3. A Discussion section. In this section, you need to analyze your counter and discuss your simulation results. You must also discuss any difficulties that you faced while working on this assignment and how you overcame them. In addition, you should also indicate what you learned after finishing this assignment.

4. Screenshots design showing 2 successive up-counts and 2 successive down-counts

5. Your conclusions
