                                       关于tie cell的认识
        关于tie cell,我刚入职不久时,曾有幸听过台湾那边的大神详细的解释和介绍,只怪自己当时太“嫩”,没有听懂,还装B不做笔记,真是后悔啊,现在只能自己去找资料了。。。
      icc是这么解释的:
      In  some designs, unused input pins cannot be tied directly to the power or
 ground net and tie-high, tie-low, or tie-highlow cells must be used。
      操作对象是unsed input pin,就是input pin什么都不接时,必须要给input pin
一个high/low 的电位。
      从器件的角度去看tie cell:
tie cell的版图构造和管级电路图结构,需要去查查相关的书籍资料。。。(未完待续)
