Identifying design problems and solving them as early in the design cycle as possible is a key to keeping projects on time and within budget. Too often, product design and performance problems are not detected until late in the product development cycle, when the product is ready to be shipped. [3]
Verification is intended to check that a product, service, or system meets a set of design specifications. [6] [7] In the development phase, verification procedures involve performing special tests to model or simulate a portion, or the entirety, of a product, service, or system, then performing a review or analysis of the modeling results.
In other words, software verification ensures that the output of each phase of the software development process effectively carries out what its corresponding input artifact specifies (requirement -> design -> software product), while software validation ensures that the software product meets the needs of all the stakeholders (therefore, the ...
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.
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 ...
Design output, including evaluation of conformance to design input requirements through: Design verification confirming that the design output meets the design input requirements ("did we design the device right?") Design validation ensuring that the devices conform to defined user needs and intended uses ("did we design the right device?")
[2] This is complex and takes the majority of time and effort (up to 70% of design and development time) [1] in most large electronic system design projects. Functional verification is a part of more encompassing design verification, which, besides functional verification, considers non-functional aspects like timing, layout and power. [3]
Electronic design automation is used extensively to ensure that designers do not violate design rules; a process called design rule checking (DRC). DRC is a major step during physical verification signoff on the design, which also involves LVS ( layout versus schematic ) checks, XOR checks, ERC ( electrical rule check ), and antenna checks.
