1·This paper introduces the VHDL top down design method including scheme determination, hierarchy division, and VHDL application taking a digital code lock design for example.

文中以数字密码锁的设计为实例，从方案的确定，各阶层的划分，VHDL的应用，介绍了VHDL自顶向下的设计方法。

2·YH TS 1 is a 32 bit embedded microprocessor designed by School of Computer in National University of Defense Technology. It is a top down design and has fully intellectual property.

银河TS 1嵌入式微处理器是国防科学技术大学计算机学院设计的32位嵌入式微处理器，完全正向设计，具有自主版权。

3·Only by taking an iterative approach where each iteration combines top-down and bottom-up design is an organization likely to achieve Process Isomorphism.

只有采用迭代的方式，在每个迭代中结合自顶向下和自底向上的设计，组织才有可能获得流程同构。

4·The approach to use case modeling can be considered a top-down approach for SOA design, where service operations are identified based on where they are needed.

用于用例建模的方法可以视为SOA设计的自顶向下方法，服务操作基于所需的场合进行标识。

5·Enterprises are free to use top-down, bottom-up, or a combination of top-down and bottom-up design methods within the framework of the models discussed.

在模型讨论的范围之内，企业可以随意使用自顶向下、自底向上、或是二者结合的设计方法。

6·XAware also gives developers the option of starting the design process with XML Schemas, an approach known as top-down design.

借助于XAware，开发者可以通过XML Schemas开始设计过程，这是一种top - down的设计方式。

7·However, by applying XSLT to the service messages, in many cases, you can map the service format of the bottom-up style messages to the top-down design.

但是，在很多情况下，通过将XSLT应用到服务消息上，可以将自下而上型消息的服务格式映射到自上而下的设计。

8·Generally, a computer system is comprised of different sub systems so a programmer needs to have some design or top-down thinking skills to see the program from the larger picture.

总的来说，一个计算机系统是由不同的“子系统”组成的，因此程序员需要掌握一些设计技巧或者自上而下的思维方法，这样才能从整体上把握全局。

9·A top-down implementation requires more planning and design work to be completed at the beginning of the project.

自顶向下的实现需要在项目开始时完成更多计划和设计工作。

10·You can start at the top — the design level, lay out your overall vision and then gradually drill down and implement the components (services).

可以从顶层，即设计层开始，布置整体构想，然后逐渐地深入并实现各个部件(服务)。
