Exam Problem: Design the following light$-$sequence generator which has

$-4$ inputs: Clock $($Clk$),$ active$-$high synchronous Reset $($Rst$),$ L and R$.$

$-4$ outputs: seg$\_$A$,$ seg$\_$B$,$ seg$\_$F$,$ seg$\_$G$.$ The segment $\backslash ($ A $\backslash ),\backslash ($ B$,$ F$,$ G$($C A$,$ C B$,$ C F$,$ C G$)\backslash )$ of the seven$-$segment display will be used in this assignment.

$-$ If Rst $=1$ at the rising edge of Clk $,$ the machine is back at the initial state where all segments are OFF.

$-$ The FSM starts from a state where all segments are OFF.

If the users change their mind about the input signals in the middle of any light sequence, I let you, as a designer, decide how to deal with this $-$ make sure you explain how you deal with this when you draw a state diagram. The segments A $->$ B $->$ G $->$ F $->$ A $->$ B $->$ G $->....$ are lit up$,$ one at a time. This sequence is repeated as long as $\backslash ($ L$=0\backslash )$ and $\backslash ($ R$=1\backslash ).$

$-(15$ pts$)$ Design the circuit $($draw its state diagram$).$

$-(30$ pts$)$ Write a Verilog file to describe your designed circuit

$-(25$ pts$)$ Write a testbench to simulate your circuit. Note: your testbench should contain at least $4$ case scenarios such as

a$)\backslash ($ L$=1,$ R$=0\backslash )$ for at least $6$ clock cycles,

b$)\backslash ($ L$=0,$ R$=1\backslash )$ for at least $6$ clock cycles,

c$)\backslash ($ L$=1,$ R$=1\backslash )$ for at least $6$ clock cycles,

d$)$ the user changes his$/$her mind about the input signals in the middle of any light sequence. Your waveform for this case should MATCH with your state diagram!

$-(7$ pts$)$ Write a top$-$level code to connect ClkDiv with your designed circuit.

$-(8$ pts$)$ Write a constraint $(.$xdc$)$ file for the top$-$level code and then download your
