求助各位大佬,最近刚学后端,使用icc2和smic180工艺库做一个收发器,我已经使用library manager结合tf文件和db文件、lef文件创建好了.ndm文件,但是在create_lib时总是显示如下警告:
- Warning: smic18_5lm.tf line 2583, unsupported technology file section 'CapTable'. It will be ignored. (TECH-001)
- Warning: smic18_5lm.tf line 2597, unsupported technology file section 'CapTable'. It will be ignored. (TECH-001)
- Warning: smic18_5lm.tf line 2611, unsupported technology file section 'CapModel'. It will be ignored. (TECH-001)
- Warning: smic18_5lm.tf line 2629, unsupported technology file section 'CapModel'. It will be ignored. (TECH-001)
复制代码 我看了下tf文件,总共是有两千多行的"CapModel"和"CapTable"都被忽略掉了,搜遍了内网外网,只知道这个问题可能和tluplus文件有关,然后我创建.ndm时读取tluplus file也没什么用,换db文件构造.ndm文件也没什么用,请问有大佬能够解答一下 ”CapModel " 和 "CapTable" section是干什么的吗,是不是创建库文件的时候有什么问题,然后有没有办法消除这些警告。
小白提前感谢各位~
补充一下,tf文件里的"CapTable”长这样:
- CapTable "poly_C_TOP_GP_14NOM" {
- wireWidthSize = 5
- wireSpacingSize = 16
- wireWidth = (0.18, 0.36, 0.54, 0.72, 0.9)
- wireSpacing = (0.25, 0.5, 0.75, 1, 1.25, 1.5, 1.75, 2, 2.25, 2.5, 2.75, 3, 3.25, 3.5, 3.75, 4)
- capValue = (
