| 摘要: |
| 针对目前FPGA厂商的EDA工具不对用户提供专用芯片测试功能,提出一种可应用于FPGA测试的导航映射方法．通过导航映射对FPGA底层硬件进行完全可控操作,精确控制FPGA逻辑资源的使用,可以对FPGA逻辑资源进行有针对性的测试,有效提高FPGA的测试覆盖率,同时在用户约束文件的指导下可以绕开FPGA硬件缺陷进行编程,实现有效的FPGA软件容错功能．本文采用128个测试配置对FPGA进行了验证,结果表明,利用导航映射方法可以得到良好的测试覆盖率． |

| Abstract: |
| Because the FPGA factories presently do not offer the special testing function in their EDA tools, this paper addresses the design of a navigated mapping method used for FPGA testing. The navigated mapping tool totally controls the basic elements and exactly controls the usage of FPGA logic resource, tests some targetable logic of the FPGA and increases the coverage of each test vector effectively, implements the FPGA software defect-tolerance function. The result is well proven in test converage through 128 test cases. |
