Abstract
With the increasing demand for non-volatile storage in embedded systems,the functional verification of embedded flash(eFlash)controllers has become a crucial step to ensure system reliability.In response to the low efficiency and poor timing compatibility of traditional directed testing in eFlash controller verification,this paper designs and implements an efficient verification platform for eFlash controllers based on the Universal Verification Methodology(UVM)and oriented to the AHB-Lite bus.The platform utilizes the core components of UVM to achieve a hierarchical architecture,and employs automated scripts and an integrated register model(RAL),adopting random constraint testing and coverage-driven strategies.This ensures verification completeness while shortening the verification cycle.The verification results show that this verification platform can effectively verify the various functions of the eFlash controller,achie-ving 100％code coverage and 100％functional coverage.关键词
