A demand driven function verification method

With the continuous growth of electronic design complexity, more and more attention has been paid to the software function verification of chips in the industry. When the traditional test methods and mainstream universal verification methodology (UVM) are adopted in the industry, they are based on test driven software function verification, resulting in strong coupling of components in the verification environment. When carrying out software function verification in multiple environments, It takes a lot of time to design different test components, which is not conducive to the realization of reusability. In this paper, a demand driven functional verification method is proposed. Using many common characteristics between requirements, the verification infrastructure components in multiple verification environments are extracted, and a reference library model of integrated verification infrastructure components is created. All test components are driven by requirements, so as to achieve 100% isolation among requirements, incentives, drivers, tests and tested parts, Create a widely used authentication pattern. Compared with UVM verification methodology, the new method has significant reusability improvement effect. It has the characteristics of independent components, few hierarchical relationships and convenient use, and can meet different needs and verification environment needs. Finally, the test results are analyzed and compared, which shows that the new method can be quickly applied to software function verification in multiple environments and improve work efficiency.
