The term Electronic System Level or ESL Design was first defined by Gartner Dataquest, an EDA-industry-analysis firm, on February 1, 2001. [1] It is defined in ESL Design and Verification [ 2 ] as: "the utilization of appropriate abstractions in order to increase comprehension about a system, and to enhance the probability of a successful ...
The system can be monitored during the execution itself (online) or after the execution e.g. in form of log analysis (offline). The verifying code is integrated into the system (as done in Aspect-oriented Programming) or is provided as an external entity. The monitor can report violation or validation of the desired specification.
In high-level synthesis, behavioral/algorithmic designs in ANSI C/C++/SystemC code is synthesized to RTL, which is then synthesized into gate level through logic synthesis. Functional verification is the task to make sure a design at RTL or gate level conforms to a specification. As logic synthesis matures, most functional verification is done ...
Software validation checks that the software product satisfies or fits the intended use (high-level checking), i.e., the software meets the user requirements, not as specification artifacts or as needs of those who will operate the software only; but, as the needs of all the stakeholders (such as users, operators, administrators, managers ...
And, validation (of the whole software product) would be equivalent to dynamic testing and intended to be applied to the running software product (not its artifacts, except requirements). Notice that requirements validation can be performed statically and dynamically (See artifact validation).
Another approach is deductive verification. [5] [6] It consists of generating from the system and its specifications (and possibly other annotations) a collection of mathematical proof obligations, the truth of which imply conformance of the system to its specification, and discharging these obligations using either proof assistants (interactive theorem provers) (such as HOL, ACL2, Isabelle ...
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.
Validation is the process of evaluating a system or component during or at the end of the development process to determine whether it satisfies specified requirements. And, according to the ISO 9000 standard: Verification is confirmation by examination and through provision of objective evidence that specified requirements have been fulfilled.
