Q2) Design a minimum state HLSM that manages access to a road that is under construction. Maximum 10 cars can pass in any one direction at a time, when there are cars waiting on the other side. • The system starts in the IDLE state • CARS LEFT = 1 if there are cars on the left side waiting to pass • CARS_RIGHT = 1 if there are cars on the right side waiting to pass • If cars arrive simultaneously on the left and on the right at the same time, the cars on the right go first. • Only one car is allowed on the road at a time. • If 10 cars have passed in one direction and there are no cars waiting on the other side, direction shouldn't be changed until a car arrives on the other side. (a) Draw the HLSM to represent the above system. (b) Draw the circuit representing the data-path of this system. (c) Draw the control unit and connect it to the data-path with correct labeling.

Q2) Design a minimum state HLSM that manages access to a road that is under construction.
Maximum 10 cars can pass in any one direction at a time, when there are cars waiting on the
other side.
• The system starts in the IDLE state
• CARS LEFT =1 if there are cars on the left side waiting to pass
• CARS_RIGHT = 1 if there are cars on the right side waiting to pass
• If cars arrive simultaneously on the left and on the right at the same time, the cars on the
right go first.
• Only one car is allowed on the road at a time.
• If 10 cars have passed in one direction and there are no cars waiting on the other side,
direction shouldn't be changed until a car arrives on the other side.
(a) Draw the HLSM to represent the above system.
(b) Draw the circuit representing the data-path of this system.
(c) Draw the control unit and connect it to the data-path with correct labeling.
