cadence仿真时spectre.out文件报错

yqiyuan

最近自己往centos7装了spectre但是没法出结果，研究了一会没研究出结果来，我的想法时spectre.cfg的路径不对，我看了下他的路径应该是/home/opt/virtuoso/SPECTRE18.10.287/tools/spectre/etc/configs/spectre.cfg才对，但是我不知道这个路径该去哪里改，我去原理图网表文件里打开input.scs好像也没找到相关可以改路径的地方。弹出来的错误如下

我的IC618是下载坛内其他朋友分享的解压出来的版本，我解压后直接bin到添加环境变量能用，然后spectre是shell脚本自动安装的然后整个文件夹复制到IC618同目录下的，因为实在找不到ic618和spectre比较新的资源了

在你的路径/home/opt/virtuoso/SPECTRE18.10.287/ 下，应该有一个softlink 是tools 指向 tools.lnx86的。如果没有，你可以手动创建一个 softlink, 命令是
cd /home/opt/virtuoso/SPECTRE18.10.287/
ln -s tools.lnx86 tools

如果这个链接已经存在，但是Spectre仍然报错，就是另外的问题。我认为你不因该把SPECTRE18和IC618装在一个$CDS_INST_ROOT 下面，因为这是按照两个软件包来Release的。也正是因为这个原因，我觉得你的Spectre装了之后没有Config好（或者本来就没装好），所i有在IC618平台上用有问题。
