Consider a sporting event where there are $4$ referees. When a call is contested, each referee must vote to support $($HIGH$)$ or reject $($LOW$)$ the call. If there is a tie, the head referee breaks the tie and makes the decision. The head referee is part of the team of $4$ referees.

Design a system for determining the final decision based on the rules given above. Your implementation must only use dataflow modeling and will have a single output representing the final decision. A HIGH value on the output represents supporting the original call while a LOW value on the output represents a rejection of the call.

Assignment:

Implement the above design utilizing the Vivado simulation tools. Make sure to include all input and output signals in your simulation and cover every possible combination of input conditions as part of your test bench.
