由于现代高速系统要求相应的高速逻辑器件,所以许多半导体厂商已经开发出了许多这样的生产线,如ACT、FACT和AS。但是,在这些系统中,线路板的布局应遵守分布参数的原理,否则,振铃(ring)、串扰以及其它一些传输线现象会使系统不能工作。要满足这一额外的要求,就有必要改变一些事情,即改变一直认为电路板只是工程问题,与逻辑设计无关。如果要开发一个高速线路板或系统,逻辑设计者必须和线路板设计者密切合作。
Because modern high-speed systems require corresponding high-speed logic devices, many semiconductor manufacturers have developed many of these lines, such as ACT, FACT, and AS. However, in these systems, the board layout should follow the principle of distributed parameters, otherwise ring, crosstalk and other transmission line phenomena will render the system inoperable. To meet this additional requirement, it is necessary to change the things that change has always been that the board is only an engineering problem, and has nothing to do with the logic design. If developing a high-speed board or system, the logic designer must work closely with the board designer.
