#lmgrd
export PATH="/home/tool/synopsys/scl/scl11.5/linux/bin:"$PATH
#start synopsys license using lmgrd
alias lmli2="lmgrd -c /home/tool/synopsys/license/synopsys.dat -l ~/syn_lic.log"
export SYNOPSYS="/home/tool/synopsys/dc/dc2008"
export SNPSLMD_LICENSE_FILE=27000@localhost.localdomain

export DVE_HOME="/home/tool/synopsys/vcs/vcs2011/gui/dve"
export PT_HOME="/home/tool/synopsys/pt/pt2011"
alias dc="dc_shell"
