刚刚学习cadence的使用,选用了smic的180的lib来仿真,但是提示下面这个error,请问是什么意思呢?
  ERROR (SFE-675): "/opt/cadence/SMIC_018_MMRF/SMIC_018_MMRF/models/spectre/ms018_v1p7_spe.lib" 4: Illegal library definition found in netlist

刚才以为可能是没有选择section,现在加上了section tt,然后error更多了。。。

    按照这个设置仿真得到的结果error更多了。。。

spectre 仿真器的model文件是*.scs格式的!一般会有一个类似ReadMe.txt的文件描述怎么设置。

回复 5# xingde
没找到这个格式啊
readme的节选是这样的

How to use SMIC SPICE models in spectre:

      Add the following statements to spectre netlist.
      
       a. Specify MOS, BJT, diode, resistor, MIM corner and model by the 'include' statement;

         include "/xxx/xxx/ms018_v1p7_spe.lib" section=tt
                                                       ^^ mos model corner

         include "/xxx/xxx/ms018_v1p7_spe.lib" section=bjt_tt
                                                           ^^ bjt model corner

         include "/xxx/xxx/ms018_v1p7_spe.lib" section=res_tt
                                                           ^^ resistor model corner

         include "/xxx/xxx/ms018_v1p7_spe.lib" section=mim_tt
                                                           ^^ mim model corner

是个比较玄学的问题,有时候上午可以仿,下午突然就不能仿了
