术语 | logic diagram engineering |
释义 | logic diagram engineering 工程逻辑图 A specific logic diagram that has been referenced or addended with detailed information relating to circuitry, chassis layout, terminal identification, etc., and showing gates, circuits, etc., used in the logic as well as the types and ratings of the circuit elements. An engineer's usual approach begins with a set of functional specifications, which he translates into a block diagram and then reduces to the level of individual gates. The completed design is assembled on abreadboard, built into a prototype, and then with a series of tests and redesigns, reduced to a form that can be manufactured in volume and sold at a profit. Meanwhile, it may be undergoing simulation on a computer as part of the design refinement. 一种特殊逻辑图,其上已经注明来源或加注上同电路、框架布局、端口识别标志等有关的详细信息。图中标出了门和电路等所用的逻辑、类型 以及电路元件的标称值。工程师常用的方法是:以一套功能技术说明书开始,按一定规则将其 变成框图,然后再到各个门电路。 整个设计装配在试验板上构成一个样机,再对其电路进行一系列测试和再设计,最后压缩 到使其能定型成批生产,销售出去获取利润,同时,对于需要精细设计的部分,也可以在计算机 上进行模拟实验。 |
