Summary

This chapter centered on the key concept of state and the fundamental difference between sequential and combinational logic:

• sequential outputs depend on both current inputs and stored past state
• in synchronous systems, state is created/held/updated under a global clock so behavior is predictable and verifiable

After this chapter, you should be able to:

• Explain how registers and register files work starting from clocks and flip-flops.
• Build and verify sequential circuits with control signals (Load/WE/Reset) in Logisim Evolution.
• Use FSMs to combine state transitions with state storage, and understand how sequential and combinational logic cooperate.
