Logic is sequential if outputs at a specified time are a function of the inputs at that time and at all preceding times. State machines are good examples of sequential logic. Other examples of sequential logic are counters, shift registers, and controllers.

Sequential logic is implemented in Verilog HDL with Always Constructs. These constructs direct the Compiler to create logic circuitry that is controlled by the construct's clock or other signals.

This section includes the following topics:

• Implementing Registers
• Implementing Counters
• Implementing Latches
• Implementing State Machines
