我的.bashrc设置为
#Design Compiler
export PATH="/eda/DC/bin:"$PATH
#lmgrd
export PATH="/eda/SCL/linux/bin:"$PATH
#start synopsys license using lmgrd
alias lmli2="lmgrd -c /eda/license/license.dat -l ~/syn_lic.log"
export SYNOPSYS="/eda/DC"
export [email=SNPSLMD_LICENSE_FILE=27000@sally85]SNPSLMD_LICENSE_FILE=27000@sally85[/email]
LM_LICENSE_FILM=/eda/license/license.dat
alias dc="dc_shell"
alias dv="design_vision"

我输入dc 后提示：Fatal: Design Compiler is not enable. (DCSH-1)

请高手教我。谢谢
