Typical Sequential Components

Typical Sequential Components

Typical sequential components consist of registers, shifters and counters. The concept of generics is often used to parameterize these components. Parameterized components make it possible to construct standardized libraries of shared models. In the behavioral description, the output transitions are generally set at the clock rising-edge. This is accomplished with the combination of the VHDL conditional statements (clock'event and clock='1'). During the testbench running, the expected output of the circuit is compared with the results of simulation to verify the circuit design.
