基于逻辑分析仪的CPLD配置向量生成方法OA

The stringent application scenarios of CPLD devices demand high-reliability testing with rigorous standards.To address issues such as the complexity and low efficiency of testing CPLD devices via host computers,a method for generating CPLD configuration vec-tors based on a logic analyzer is proposed.Using a domestic CPLD as an example,this method employs a logic analyzer to capture the JTAG download configuration data in real time.Through protocol decoding and in-depth analysis of the decoded configuration data,con-figuration vectors are generated based on the SVF standard statement format.The configuration vectors conversion and online configura-tion testing verification using ATE were completed.The test results effectively demonstrate the correctness of the generated configura-tion vectors and the feasibility of the proposed method,providing significant guidance for the subsequent use of ATE in automated mass production testing of CPLD devices.
