Tightening the Loop on Coverage Closure

ABSTRACT

Using a methodology such as graph-based intelligent testbench automation to efficiently create verification scenarios and stimuli is a powerful way to enhance advanced verification environments to reduce common verification headaches. It can help to free up resources--in terms of time, people and hardware--to focus on the challenges of realizing a more ambitious verification plan and of creating better functional coverage metrics. This enables the verification team to ensure that the device has been exercised in a far more comprehensive manner, thereby reducing the resulting defect density. This paper explores a unique solution to two challenges: definition of adequate coverage measurement and the setup of efficient automated testbenches.
