PARA-075 (error) Could not resolve net

时间:10-02 整理:3721RD 点击:

做PT的时候,用starRC提取的spef文件反标注到STA中,发现有些线网不能resolved,提示错误如下所示:
Information: Derived library resistance unit is 1.000000 Kohm (Time unit is 1 ns, and Capacitance unit is 1.000000 pF). (DES-028)

starRC提取出来的net却是icc产生的.v文件里头所没有的,没搞懂。
是我Icc 里头生成的.v文件不对么?先前有做过一次,是OK的,后来有修改过tcl,后就成这样了。
参考过http://bbs.eetop.cn/thread-319247-1-1.html,仍没法解决,各位大神请支招啊。

顶起,ICC:201003,PT:201006,STAR:201006

没大神搭理啊,呼呼,再次顶起。
好像是因为我修改了tcl引起的,但就是不知道是哪一步引起的。starrc提取的spef,多了一个net,死活对不上。更多的是因为hierarchical的原因引起的,好像。
我把set_dont_touch [list I0/s_clock1]屏蔽掉之后,就仅剩下这个错误了。
Error: Could not resolve net 'I210/net30740'.(PARA-075)

修改了hierarchical的一个连接线结构,问题得以解决。

请问是怎么修改的?
