Design the entity declaration for a simple $4-$bit binary counter. The counter should have the following interface. Name the entity Simple$\_$Counter. Declare the appropriate input and output ports with their respective data types and sizes as described in the problem statement. Comment each line of your entity declaration to describe the purpose of each port. clk: A $1-$bit input for the clock signal. reset: A $1-$bit input to reset the counter to zero. enable: A $1-$bit input that enables the counter to increment. When enable is low, the counter should not increment. count: A $4-$bit output that shows the current count value.
