应用软件消除毛刺现象

Using Software to Eliminate Glitch

由于竞争而产生的毛刺会破坏数字系统的设计,因此必须避免。传统的解决方法有其不足之处。随着可编程器件的广泛应用和EDA技术的飞速发展,通过在线编程就可消除毛刺现象,并最终获得稳定合理的设计。以Altera公司的MaxplusⅡ为开发平台,选用EPF10K10系列器件,就如何应用软件编程消除毛刺现象做一介绍。

The glitch produced owing to competition will destroy the design of digital system , therefore it should be avoided . The traditional way of solvin g the problem has its defects . With the wide use of programmable logic device a nd the fast development of EDA technology, the glitch can be eliminated by on-line programming and steady and reasonable design can be achieved . With Maxplus Ⅱ of Altera Company employed as the designing platform and the series of EPF10 K10 device selected , the present article gives an introduction on how to elimin ate glitch by software gramming.
