分享一些电子工程相关英语句子。 1.The design of a high-performance, full-custom integrated circuit (IC) is, of course, a difficult task. In full-custom IC design, everything, down to and including individual transistors may be designed (although libraries of parts are, of course, used). 1.高性能，全定制集成电路(IC)的设计当然是一个困难的任务。在全定制集成电路的设计中，所有事情，甚至是单个晶体管都需要被设计(当然，尽管要用到一些库)。 2.For many years, however, it has been possible to build semi-custom integrated circuits using gate arrays. A gate array, as its name suggests, is an integrated circuit on which an array of gates has been created. The design of an application-specific integrated circuit (ASIC) using a gate array therefore involves the definition of how the gates in the array should be connected. 2.但是，多年以来，可以使用门阵列构建半导体集成电路。门阵列，正如其名，是由许多逻辑门所构建的集成电路。因此，使用门阵列进行专用集成电路的设计包括定义列阵中的逻辑门是如何连接的。 3.In practical terms, this means that one or two layers of metal interconnect must be designed. Since an integrated circuit requires seven or more processing stages, all the processing steps other than the final metalization can be completed in advance. Because the uncommitted gate arrays can be produced in volume, the cost of each device is relatively small. |
