求助使用calibre提取spef的问题

请教各位大神，由于缺少starRC必要的文件，我用calibre提取icc后gds的spef，然后再用pt做时序分析。
在calibre中将.v转成了cdl格式，cdl和.v的线名是一样的，然后用cdl和版图做了lvs，接着提取spef，设置了gate_level级，也写了hcell，并且输出文件格式选了spef+Primetime，但是输出的spef没法在PT中实现反标。PT报错：error：could not resolve net 'inst_A/inst_B/U1/net1'。最后一个都没反标上去，请问这是什么问题呢?生成的spef文件部分如下：
inst_A/n1
0/6634
0/6625
0/6627
inst_B/n2
inst_C/n3
其中有0/6634这类信息，在PT中会报错invalid capacitor （0/6634: A2 5.09932e-05） on net inst_A/n1。请问为什么会产生0/6634这类信息呢?PT好像并不能识别它们

小编能贴一下hcell的格式么

就是两列标准单元名，如：
AD2D1AD2D1
INV1INV1
AOI1AOI1

太复杂了， 直接用icc write spef不就好了， 或者加点margin，直接用icc signoff也可以的
和pt signoff差不多

哦，好的，多谢，我现在就是用的icc来write spef，请问margin怎么加的?
而且，我发现icc和pt报出的时序违例不一致，有些icc中认为是setup问题的，pt没有报，对hold的报告也不一致。请问哪个更可靠些?
我使用的pt是2009版本的，用fix_eco_timing后，插入的buffer特别多，多的有些离谱，超过了要求的面积，返回icc就没法完成插buffer，是不是这个版本的pt的fix_eco功能还不够完善?
我是新手，多谢指导了

好东西

谢谢你们的介绍，我也知道了！
