Examples
- A plan of design for test based of boundary scan testing is introduced for this signal processing system
接着，提出了该信号处理系统基于边界扫描的可测性设计方案。 - As one of the design for testability technology , boundary scan test ( bst ) fixes boundary scan cells between the device pins and core logics . thus , the bsc acts as the virtual test probe that carries out the test stimulus and captures the test response
作为一种结构插入的可测性技术,边界扫描测试( bst )技术将边界扫描寄存器单元安插在集成电路内部的每个引脚上,其作用相当于设置了施加激励和观测响应的内建虚拟探头。 - Chapter two detailedly presents the design of the boundary scan testing system which is in accordance with ieee . 1149 . correspondingly two special - used data registers are added , one of which is the scanning chain register and the other is the child scanning chain control - register
文中第二章按照ieee . 1149标准详细设计了边缘扫描测试系统，相应增加了两个专用数据寄存器，其中一个为扫描链寄存器，一个为扫描子链控制寄存器。 - The majority of the test vectors are used to check the connection of the pins of the device . those vectors for connection test can be removed from the vector base for the device under test when deltascan is applied together with boundary scan test . the total vectors are therefore eliminated
测试矢量中大多数是用于测试引脚之间是否有短路或有引脚开路情况的，引入deltascan测试ic的引脚的开路和短路情况后，就可从xc5210 _ tq144的测试矢量集中去掉合并与短路，开路测试有关的测试矢量，进一步减少了边界扫描所需的测试矢量。 - In the logic design , the fundamentals and characteristics of ieee std . 1149 . 1 specification and usb protocol are introduced first of all . according to altera ’ s fpga cyclone , it analyzes the architecture and jtag instructions of boundary scan test ( bst ) . then the dissertation analyzes how to program cyclone device and offer the scheme of the design which is realized in verilog hdl by modelsim and quartus ii software
在接口逻辑设计中,首先分析ieee1149 . 1标准和usb协议,理解边界扫描测试和usb数据传输的工作方式,然后针对altera公司的fpga器件cyclone ,通过分析它的边界扫描测试结构和各种jtag指令,研究它的编程过程和编程特点,并提出设计方案。
