Design for verification (DfV) is a set of engineering guidelines to aid designers in ensuring right first time manufacturing and assembly of large-scale components.The guidelines were developed as a tool to inform and direct designers during early stage design phases to trade off estimated measurement uncertainty against tolerance, cost, assembly, measurability and product requirements.
An engineering verification test (EVT) is performed on first engineering prototypes, to ensure that the basic unit performs to design goals and specifications. [1] Verification ensures that designs meets requirements and specification while validation ensures that created entity meets the user needs and objectives.
Test coverage in the test plan states what requirements will be verified during what stages of the product life. Test coverage is derived from design specifications and other requirements, such as safety standards or regulatory codes, where each requirement or specification of the design ideally will have one or more corresponding means of verification.
The hardware design and hardware verification need to be done independently. The hardware designer works to ensure the design of the hardware will meet the defined requirements. Meanwhile, the verification engineer will generate a verification plan which will allow for testing the hardware to verify that it meets all of its derived requirements.
In scan-design, registers (flip-flops or latches) in the design are connected in one or more scan chains, which are used to gain access to internal nodes of the chip. Test patterns are shifted in via the scan chain(s), functional clock signals are pulsed to test the circuit during the "capture cycle(s)", and the results are then shifted out to ...

In the design verification role, SystemVerilog is widely used in the chip-design industry. The three largest EDA vendors ( Cadence Design Systems , Mentor Graphics , Synopsys ) have incorporated SystemVerilog into their mixed-language HDL simulators .
