vcs编译出错，用-full64命令后无法生成simv文件

本人小白，用VCS编译.v文件出现如下问题：[dmy@dmy src]$ vcs tb_test_top.v test_top.v
Warning-[LNX_OS_VERUN] Unsupported Linux version
Linux version 'CentOS release 6.5 (Final)' is not supported on 'x86_64'
officially, assuming linux compatibility by default. Set VCS_ARCH_OVERRIDE
to linux or suse32 to override.
Please refer to release notes for information on supported platforms.

Please check whether 'VCS_HOME' is incorrect; if not, see below.
The error message report included the following additional information:

Perhaps vcs hasn't been installed for machine of type "linux".
Or the installation has been damaged.
To verify whether vcsJ-2014.12 supports machine of type "Linux 2.6.32-431.el6.x86_64",
please look at ReleaseNotes for more details .
We determine the machine type from uname; maybe uname is incorrect.
You can fix installation problems by reinstalling from CDROM
or downloading it from the Synopsys ftp server.
For assistance, please contact vcs technical support
at vcs_support@synopsys.com or call 1-800-VERILOG

在网上查了一下，有人建议添加-full64，如下：
[dmy@dmy src]$ vcs -full64 tb_test_top.v test_top.v

但是这样做在当前目录下仅生成了csrc文件夹和simv.daidir文件夹，并没有需要的simv文件
有没有人知道是哪里出了问题呀，跪谢！

how to generate vpd file in vcs

好像还每到生成vpd那一步

这个问题，应该是环境变量没有设对

小编问题解决了吗

好像是os是centos, 却安装了x86_64版本的软件。
不知道可以兼容吗。
在设置VCS_HOME时，试一下：
set VCS_ARCH_OVERRIDE llinux
