the bit vectors of type std$\_$logic$\_$vector of any length are converted into a text representation $($delivery of the source program of the tested Str function$).5$P

c$)$ Write a test program that contains a variable a of type std$\_$logic$\_$vector$(3$ downto

$0)$ initialized with $"$X$10$U$",$ the most significant bit has the value $\text{'}1\text{'},$ then the entire bit

Assigns the value $"1001"$ to vector and outputs all values $$with report. Target output:

$...($report note$)$: Issue $1$: X$10$U

$...($report note$)$: Issue $2$: $110$ U

$...($report note$)$: Issue $3$: $1001$
