I think design verification is important, because in the initial stages of design verification is a key quality assurance technique. As the design effort progresses, verification activities become progressively more comprehensive. Verification is a theoretical exercise designed to make sure that no requirements are missed in the design. For some technologies, verification methods may be highly standardized. In other cases, the manufacturer may choose from a variety of applicable methods. In a few cases, the manufacturer must be creative in devising ways to verify a particular aspect of a design. Some manufacturers erroneously equate production testing with verification. Whereas verification testing establishes conformance of design output with design input, the aim of production testing is to determine whether the unit under test has been correctly manufactured. In other words, production testing is designed to efficiently screen out manufacturing process errors and perhaps also to detect infant mortality failures. Typically, a small subset of functional and performance tests accomplish this objective with a high degree of accuracy. Therefore, production testing is rarely, if ever, comprehensive enough to verify the design. The purpose of Design Verification is to confirm your Design Outputs meet your Design Inputs. This is why you have to think about Design Verification when defining Design Inputs.
There is continuous innovations as every company looks for better and efficient ways to improve efficiency and productivity in Verification. This is the only way an increasingly complex design can be successfully taped out in a market driven schedule. Companies can also develop a software solution to improve this design verification.
