cadence AMS 混仿全加器时报错

cqu_luj

Warning from spectre.
    WARNING (SPECTRE-135): No analysis specified.

spectre terminated prematurely due to fatal error.
ncsim: *E,RNALER: Simulation terminated due to analog error.

请问这个是什么原因呢？？？

查看ahdlcmi.out文件，报错如下：

ld: BFD (GNU Binutils) 2.20 internal error, aborting at ../../binutils-2.20/bfd/reloc.c line 446 in bfd_get_reloc_size

查看ahdlcmi.out文件，发现报错如下：

我安装的MMSIM151 和 INCISIVE151，分别打开下面路径发现：
/cadence/MMSIM151/tools.lnx86/cdsgcc/gcc/  下面有一个4.8文件，bin文件中cdsgcc中gccversionfull显示是4.8.3，如果没有4.8.3就用4.1.2
/cadence/INCISIVE151/tools.lnx86/cdsgcc/gcc/  下面有4.1和4.4两个文件，bin文件中cdsgcc中gccversionfull显示是4.4.5 ，如果没有4.4.5就用4.1.2

难道是这两个分别需要的gcc版本不同？所以混合仿真失败了？

问题解决
解决方案链接：http://bbs.eetop.cn/thread-635921-1-1.html
原文：
gcc 版本不兼容问题
把下面这个目录里的gcc备份一下"gcc_bk"，删除gcc,

/opt/cadence/INCISIVE152/tools.lnx86/cdsgcc/gcc/4.8/bin$


在/usr/bin里找到gcc

建立软连接：
/opt/cadence/INCISIVE152/tools.lnx86/cdsgcc/gcc/4.8/bin$ sudo ln -s /usr/bin/gcc ./gcc
完美解决

要开-64bit选项。
开了之后，下面这两个err和warning消失
ERROR VACOMP-1008 Cannot compile ahdlcmi module library

WARNING VACOMP-2397 Comilation failed when using pipe build
