China has implemented new courses in a few years, the study of middle school teachers teaching and students studying math on the investigation at this stage Instructional Design Research expounded on the need from classroom teaching and learning theories analysis, to find guidance in the design of classroom teaching under the new curriculum theory and classroom teaching on the design analysis of the whole process; From the typical class (class mathematical concepts and mathematical theory classes and study complicated math classes, the study of mathematics learning courses, open learning mathematics classes, cooperative learning math lessons) teaching the practice of design study, initial design, this is my classroom teaching design in recent years the practice of summary, the results of this study reflect.

新课程在我国已实施好几年了，本研究通过对初中教师与学生数学教学情况的调查，阐述研究现阶段课堂教学设计的必要性；从课堂教学理论、学习理论的分析中，寻找指导新课程下课堂教学设计的理论，并就课堂教学设计的全过程进行剖析；从几种典型课(数学概念课、数学原理课、数学复习课、数学研究性学习课、数学开放探究课、数学合作学习课)的课堂教学设计的实践研究中，提出初步的设计思路，这既是本人近年来课堂教学设计的实践总结，也是本研究的成果体现。

First design a reasonable XML Schema structure and under the restriction of XML Schema use XML to describe the UML class diagram and the related specification, and then extract the test specification of method from XML test script. Test specification refers to predicate sequences in the form of conjunctive normal form, extracted from basic constraint conditions of variables included in test scripts and expected outputs. Each conjunctive normal form can be transformed to an inequation set, and adopt 1×1 domain test strategy to every inequation set to produce the domain test matrix, which in turn produce the test case.

首先设计合理的XML Schema结构，并在该XML Schema的有效性约束下，用XML对UML类图及相关性约束进行脚本描述；其次对XML测试脚本进行分析，提取方法的测试规约说明，所谓测试规约说明就是从测试脚本中包含的变量的基本约束条件以及期望输出中抽取得到的以合取范式形式存在的谓词序列；每一合取范式对应一个不等式组，对每一个不等式组采用1×1域测试策略，生成域测试矩阵，最终得到测试用例。

Some methods aiming at the two problems have been researched. First, the optimal number of ATE site can be calculated based on a cost model of DAT-ATE. Second, the problem of test schedule which is equitant with two-dimensional Bin-Packing problem is presented. Then a TCG denotation satisfied with T-admissible rule is more convenient for combinational optimization. With Simulated annealing algorithm, better test scheduling results can be achieved; but there is no great optimization space because the efficiency of scheduling is greater than 90%. Third, A novel test compression method——Multi-capture testing is proposed to compress the stimuli. And the ATPG results show that MC achieves high compression ratio which is greater than 90% in some large-scale circuits. MISR, widely used in LBIST, is employed to compress the responses. The aliasing analysis demonstrates that the fault coverage reduction is little due to the existence of aliasing. Fourth, an improved TIC (called S-TIC) aiming at structured test is proposed based on ARM's TIC. A MC scheduling algorithm is proposed to compute the SoC test time and combine MC vectors to SoC test vectors. The scheduling results shows that test time is greatly reduced when using the proper scheduling priority.

首先，给出了低成本ATE的成本模型，根据此模型得到最低测试成本时系统级测试调度的基本参数——测试Site数；其次，本文将DAT-Scan方式的SoC测试调度等价为两维BP问题，为有效地求解该问题，将该BP问题表示为TCG图并通过模拟退火算法解决其求解过于复杂的问题，调度的结果表明该方法在测试时间上有一定改善，并指出DAT-Scan测试调度效率已经大于90％，进一步优化的空间较小；第三，本文尝试通过测试压缩来解决激励所需的测试带宽，提出了Multi-capture结构并解决了MC测试过程中的&矢量&退化问题，MC测试的ATPG结果表明其测试压缩率很高（大电路接近90％）；第四，在激励获得很高压缩比的情况下，测试响应也需压缩，本文采用LBIST中常用的MISR作为MC测试的响应压缩电路，理论分析和实验结果都证明了MC测试的别名对故障覆盖率影响较小（小于2％），并对两类别名的成因做了具体分析；第五，在MC测试及其响应压缩的基础上，本文改进了ARM公司的测试控制器TIC使之适合于MC测试，为了解决MC测试矢量合成问题，本文抽取了MC测试模型，通过固定优先级的MC测试调度模拟将MC矢量合成为ATE矢量，并模拟出了总的MC测试时间。
