      Short description: In this exercise, students will be asked, through a series of steps, to design a combinational circuit which implements a conditional logic – it will perform a different calculation on its inputs depending on the values of certain selection bits. This exercise is also showing how to build on previously built system and expand it by adding additional combinational components. It is started by designing a very simple combinational circuit, a full adder, and by designing students will repeat all the steps needed to simulate and synthesize circuit. Afterwards, students will extend this circuit with more components, culminating with a complex combinational circuit.
