摘　　要：阐述基于通用验证方法学自主开发的一款用于ONFI 4.0接口标准的NAND闪存验证IP。通过配置类的方法实现验证IP的灵活可配,结合通用验证方法学中分立的模块化设计方法,使得激励的产生和驱动相分离,实现验证IP的通用性驱动功能。IP中还集成参考模型和计分板模块实现验证结果的对比输出。最后,将验证IP嵌入真实验证环境中检验IP功能的可靠性,确认了验证IP对于验证效率的大幅提升。This paper describes a NAND Flash memory verification IP developed independently based on general verification methodology for the ONFI 4.0 interface standard.It achieves flexible and configurable verification of IP through the method of configuring classes,combined with the modular design method in general verification methodology,which separates the generation of incentives and drivers,and realizes the universal driving function of verifying IP.The IP also integrates reference models and scoreboard modules to achieve comparative output of verification results.Finally,it verifies the reliability of verifying IP functionality in a real verification environment by embedding IP,confirming the significant improvement in verification efficiency of verifying IP.
