摘要
为完成对日益复杂的目标器件的测试工作,在研究边界扫描测试技术和IEEE1149.7标准的基础上,对符合IEEE1149.7标准的边界扫描测试控制器进行设计构建,重点介绍控制器中命令控制功能模块的设计实现。基于Quartus II应用平台进行设计,通过Modelsim完成仿真验证,仿真结果表明,该命令控制模块能够正确产生符合TAP.7控制器命令标准的测试信号。
To complete the testing of the increasingly complex target devices, based on the in-depth study of IEEE 1149. 7 stan-dard and the technology of boundary-scan test, the boundary-scan test controller which met the IEEE 1149. 7 standard was de-signed and constructed. The design and implementation of command control function module in the controller was mainly intro-duced. The design was based on the Quartus II application platform, and through the Modelsim, the simulation and verification was completed Results of simulation show that the command control module can correctly generate the test signals in compliance with the TAP.7 control command standard.
