此时是缺乏xterm，在root账户操作：yum install xterm -y，即可安装xterm。

2.  OA数据库相关设置

在configure过程中会不断跳出弹框，其中之一如下：

Proceeding with configuration of lfvhdComp

synergy users must install these libraries

install valid library and sim primitives?(cr=n):y

install XL library and gate primitives?(cr=n):y

此处也可以选择n，即不安装这些libraries

Prepare libraries for AMS Designer

1) Add an IUS installation directory to path

2) Quit

选'2'退出

Welcome to the OpenAccess 2.2 Configuration Utility.

......

'enter'继续，出现下面选项，不用改变OA的默认位置，所以输入n

Do you want to use a different OpenAccess installation (y/n/q)?[y]：n

3.  安装完成后启动时可能会出现如下错误：

virtuoso:   ERROR: The command  .../oa_v22.41.004/bin/sysname returned an error status: unknown

virtuoso:    INFO: Note that OpenAccess (OA) requires running the Configure phase.

virtuoso:          See the "OpenAccess Installation and Configuration Guide" before

virtuoso:          you complete the configuration step. This manual is included with

virtuoso:          the Cadence product documentation.

此时可尝试在.bashrc中加入  export W3264_NO_HOST_CHECK=1 和 export OA_UNSUPPORTED_PLAT=linux_rhel50_gcc48x 。

其中OA_UNSUPPORTED_PLAT对应具体参数名称要和/.../cadence/installs/IC61X/oa_v22.XX.8/lib/文件夹具体名称相符，

例如，.../lib下若存在linux_rhel40_gcc44x_32和linux_rhel40_gcc44x_64两个文件夹，那么要改为 export OA_UNSUPPORTED_PLAT=linux_rhel40_gcc44x。

若为.cshrc的话，格式为 setenv W3264_NO_HOST_CHECK 1 和 setenv OA_UNSUPPORTED_PLAT linux_rhel50_gcc48x 。
