谁来拯救我？ic5141 usr6安装困惑

最经从eetop下载了一个解压就可以使用的IC5141 USR6好开心的。小编大人说了只要自己配置license和.bashrc即可。链接如下http://bbs.eetop.cn/viewthread.php?tid=288069&highlight=ic5141
我自己装了个win7和redhatlinux6.4双系统，我把tar格式的解压包直接放到
linux下解压了。解压出来的文件被我拖到了/home/candence(在拖动之前已近执行过chown -R ghr /home,ghr为非root用户)
在ghr用户下，我把附件中的license文件首先修改为（只改了前两行，后面没改，license太长只显示了前几行示意一下）
SERVER localhost ANY 27000
DAEMON cdslmd /home/candence/ic5141/tools/bin/cdslmd
FEATURE 100 cdslmd 9.500 permanent uncounted DDEA36A361DDCF020B56 HOSTID=ANY
FEATURE 111 cdslmd 9.500 permanent uncounted ED1A36935FDBD0060C52 HOSTID=ANY
FEATURE 200 cdslmd 9.500 permanent uncounted DDEA369362DCCF050C53 HOSTID=ANY
FEATURE 206 cdslmd 9.500 permanent uncounted ED4A36D35CD6DFFF0C53 HOSTID=ANY
FEATURE 207 cdslmd 9.500 permanent uncounted ED7A363359D3D7000C53 HOSTID=ANY
FEATURE 223 cdslmd 9.500 permanent uncounted ED3A36934BD9D5020E67 HOSTID=ANY
我在ghr用户下，配置了.bashrc
# .bashrc
# Source global definitions
if [ -f /etc/bashrc ]; then
. /etc/bashrc
fi
# User specific aliases and functions
###############
export CDSHOME=/home/candence/ic5141
export CDSDIR=$CDSHOME
export CDS_ROOT=$CDSHOME
export CDS_INST_DIR=$CDSHOME
export CDS_INSTALL_DIR=$CDSHOME/tools/dfII
export LM_LICENSE_FILE=$CDSHOME/share/license/license.dat
export PATH=$CDS_ROOT/tools/binCDS_ROOT/tools/dfII/binCDS_INSTALL_DIR/binCDS_ROOT/tools/spectre/bin:$PATH
export CDS_Netlisting_Mode=analog

然后我就保存。启动终端 输入icfb&显示command is not found感觉该做的都做了，为什么连界面都看不到呢
