摘　　要：本文从验证平台模型的构建出发,完成了对一款USB2.0 IP核的功能验证。文中列举了部分验证代码和实例,在测试用例中着重对UTMI接口,微处理器接口和RAM接口等进行了详细描述,最后给出了仿真波形和验证结果报告,从中可以看出USB2.0 IP核的代码覆盖率达到了100%,结果令人满意。文中对验证方法学进行了研究和实践,实现了测试向量的可读性,验证结果的自动生成和可观测性,验证思想可以在相关设计中复用。With the construction of verification testbench model, we performed function-verification based on a USB2. 0 IP core in this paper. Also some real codes and cases are listed here. In particularly, the UTMI interface, macroprocessor interface and RAM interface are described in the test examples. We reach a conclusion of simulation wave and verification report, from which we find a 100% percentage of code-coverage of this core. The test vector has a feature of readability, and the verification result is created automatically. In addition, it can be reused in relative design.
