我看了相关手册,进行最简单的Pure Recharacterization Flow,
1. 无法进行基本的lab实验
按照Lab跑会卡在characterization 的stage。
Lab1_library_recharacterization
前面一切正常……
Info: Tue Feb 02 17:53:27 CST 2021: Begin characterize stage
Information: Interrupting current command. (INT-2)
Information: One more interrupt will exit process. (INT-3)
Information: Process terminated by interrupt. (INT-4)
Info: [CDPL] Shutting down CDPL master.
(然后整个terminal就卡死了)
2. 也跑不通自己的flow
我将文件替换成我自己的库,然后发现没有netlist,就是只有lvs的netlist。这个库有两个问题,1. 是一整个文件,不像siliconsmart要求的一个文件夹,每种module 一个模块; 2. 非常粗糙和简单,不是建库需要的包含后端参数的cdl 文件。
然后按照帖子 关于用SiliconSmart 做Re-characterization 网友的建议,我将库拆开,写了一个简单的cdl文件,然后运行就提示错误。
我拆出来的cdl文件:
.subckt AD42M2TM CO ICO S A B C D ICI VDD VSS
MN0 VSS 8 ICO VSS N_12_LPRVT w=0.3u l=0.06u
MN1 2 A VSS VSS N_12_LPRVT w=0.12u l=0.06u
MN2 VSS B 2 VSS N_12_LPRVT w=0.12u l=0.06u
MN3 31 B VSS VSS N_12_LPRVT w=0.12u l=0.06u
………
MP26 VDD ICI 17 VDD P_12_LPRVT w=0.20u l=0.06u
MP27 CO 20 VDD VDD P_12_LPRVT w=0.42u l=0.06u
.ends AD42M2TM
