提出一种基于混沌序列的时序数字电路的内建自测试(BIST)技术。采用混沌logistic映射模型迭代运算产生具有白噪声特性的"0-1"随机测试序列,将其作为数字电路内建测试的自动测试图形,并利用循环冗余校验(CRC)特征分析电路分析输出响应,从而得到混沌序列测试图形的响应特征码,通过特征码的不同来检测故障。实验研究表明,由于混沌迭代序列测试图形的施加顺序不唯一,因此对于时序数字电路的故障检测而言,能够比普通M序列测试的故障检测率更高,易于BIST技术实现,并适合于FPGA等大规模可编程逻辑电路的自动测试。
This paper proposes a realization method of （Build In Self Test, BIST） technique of sequential circuits based on chaotic sequence. ＂0-1＂Random sequences with the white noise characteristics which generate by chaotic logistic map model suite as digital circuits test pattern. Test response signature of chaotic sequence are obtained from the output response characteristic analysis of （Cyclic Redundancy Check,CRC） circuits. Studies have shown that the chaotic iterative sequence test pattern is not unique to impose order especially for sequential circuits, so the method presented in this paper fault detection rate is greater than that of M sequence and easy for realization of BIST, and suitable for large-scale FPGA and other programmable logic circuits automatic testing.

图形用户界面的质量直接影响整个软件系统的有效性和实用性，一般采用提取模型的方法对图形用户界面进行测试，目前常用的模型为事件流图和事件交互图，但是事件流图转换成事件交互图的算法较为复杂，为此，提出一种转换算法，对图形用户界面事件进行明确划分，利用模态窗口事件的特殊性优化原有算法。测试实例结果表明，该算法可用于图形用户界面，且与Memon算法相比，能更高效地获得更准确的数据。
The quality of Graphical User Interface ( GUI ) directly affects the reliability and usability of the entire software system. When testing the graphical user interface,it generally adopts the method of extracting model,and the frequently models based on the graphical user interface are Event Flow Graph( EFG) and Event Interaction Graph( EIG) . However,the algorithm of EFG into EIG is complex,this paper proposes an algorithm. In this paper,the GUI events with a specific division and the use of the special nature of the modal window event optimize the original algorithm. It indicates the new algorithm can be used for GUI and the obtained data is more accurate and more efficient with the real cases than Memon in GUI.

本文对静态随机存储器(SRAM)总剂量辐射引起的功能失效进行了六种不同测试图形下的测试.利用不同测试图形覆盖的出错模式不同,通过对比一定累积剂量下同一器件不同测试图形测试结果的差异,以及对失效存储单元单独进行测试,研究了总剂量辐照引起的SRAM器件功能失效模式.研究表明:器件的功能失效模式为数据保存错误(Data retention fault)且数据保存时间具有离散性,引起数据保存错误的SRAM功能模块为存储单元.通过对存储单元建立简化的等效电路图,分析了造成存储单元数据保存错误以及保存时间离散性的原因,并讨论了该失效模式对SRAM总剂量辐射功能测试方法的影响.

This paper presents the design idea and implementation framework to share graphics workstation with virtual desktop and GPU pass-through, as well summarizes the use scenario and performance analysis. The virtualization technology helps creating standalone virtual desktops for multi-users who share CPU,memory and storage resources of graphic workstation, while the pass-through technology is used to assign GPUs to different desktops, thus making it possible to share the graphic workstation with multiple graphics cards among equal number of users. Graphics designers connect to their own desktop and run graphics intensive applications from traditional PCs,thin clients or even intelligent devices. Test results show that the performance can be ensured because the graphic processing is finally done on the pass-through physical graphic card.
