Develop a logic circuit in VHDL using quartus that meet the following requirements:
In a certain chemical-processing plant, a liquid chemical is used in a manufacturing process. The chemical is stored in three different tanks. A level sensor in each tanks produces a HIGH voltage when the level of chemical in the tank drops below a specified point.
Design a circuit that monitors the chemical level in each tank and indicates when the level in any two of the tanks drops below the specified point.
