Design Verification Testing
Before design verification testing dvt during early phases of the development process engineering verification testing is often executed to prove an element of the design.
Design verification testing. Design verification includes unit and primary integration level testing. This ensures that the concept is developing along the right lines and a thorough job here will save time and money before costly manufacturing decisions are locked in. The focus of this post and the relevant terms for design controls are design verification and design validation. It consists of the following areas of testing.
Design verification testing dvt definition. Any design is therefore subject to detailed verification long before manufacturing begins and to thorough testing following fabrication. Certain aspects of design validation can be accomplished during the design verification but design verification is not a substitute for design validation. Design verification test dvt is an intensive testing program which is performed to deliver objective comprehensive testing verifying all product specifications interface standards original equipment manufacturer oem requirements and diagnostic commands.
So from this point forward in this post if you read verification i m referring to design verification and validation refers to design validation. The ultimate goal of design verification is to avoid the manufacturing and deployment of flawed designs. Large sums of money are wasted and precious time to market is lost when a microchip does not perform as expected. I m only focusing on these versions for the time being.
Verification is intended to check that a product service or system or portion thereof or set thereof meets a set of design specifications. As soon as the first prototype is built the product must begin testing to assure that it meets all of its specifications verification. Design validation follows. 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.
