使用中断处理的验证平台设计

Design of Verification Platform Using Interrupt Processing

根据主流的通用验证方法学,将中断处理思想融合到验证平台的设计当中。为了直观测试模块的性能,数据的驱动与采集的速率可自由控制,如果过程中出现异常,通过接口内部设置的定位计数器,可快速进行现场还原。将寄存器模型通过指针传递与参考模型共享,保证了设计模块与参考模型的寄存器域值一致性。经脚本处理化之后,可快速创建通用的测试用例。与传统方法相比,能够快速搭建验证平台,减少验证周期,提高验证效率并具有良好的复用性。

This paper integrates the concept of interrupt processing into the design of the verification platform based on mainstream general verification methodologies.In order to intuitively test the performance of the module,the rate of data driving and collection can be freely controlled.If an exception occurs during the process,the scene can be quickly restored through the positioning counter set in the interface.The register model is passed by pointer and shared with the reference model,ensuring the consistency of the register domain values of the design module and the reference model.After script processing,general test cases can be quickly created.Compared with traditional methods,it can quickly build a verification platform,reduce the verification cycle,improve verification efficiency,and have good reusability.
