1.libelf.so.1问题：软件中心查找libelf,安装libelf-dev,libelf1:i386
2.veriloga编译问题，查看日志，发现mpstat命令没有，安装sysstat解决。
3.
ERROR (VACOMP-1008): Cannot compile ahdlcmi module library. Check
the log file
input.ahdlSimDB/bsource_1.input.ahdlcmi/Linux2.6.32-25-generic+gcc/../ahdlcmi.out
for details. If the compiler ran out of memory, use 'setenv
CDS_CMI_COMPLEVEL 0', and try again. If the reason for the failure was a
syntax error, contact your Cadence Customer Support representative
Ubuntu默认sh只想dash，所以不支持-h参数，只要将sh默认指向更改为bash，仿真就不会再出现上述问题，修改方法为：
sudo dpkg-reconfigure dash
出现询问是否使用dash界面时，选“NO”即可
Bsource compilation is enabled by default. If you are making frequent changes to bsource
expressions used in your design, the overhead of the compilation step may become an issue. To turn off
compilation
set the CDS_AHDLCMI_ENABLE shell environment variable to NO e.g:
setenv CDS_AHDLCMI_ENABLE NO
To re-enable bsource compilation set the CDS_AHDLCMI_ENABLE to YES e.g:
setenv CDS_AHDLCMI_ENABLE YES
or unde?ne the CDS_AHDLCMI_ENABLE environment variable e.g:
unsetenv CDS_AHDLCMI_ENABLE
如果用的是csh
在cshrc中设置
在环境变量里加 LD_LIBRARY_PATH
export LD_LIBRARY_PATH=$CDS_ROOT/tools/lib： $PATH才可以，否则会有
error while loading shared libraries: libCdsXmotif. so.2: cannot open shared object file: No such file or directory
$CDS_ROOT/tools/plot//samples/cdsplotinit.sample只有几个plotter，不过还是可以用的。
