    installing&running cadence IC610 on kubuntu 7.04

    ic610 install before starting icfb,you'd better make your license work first.well,add "alias lmli '$CDS_ROOT/tools/bin/lmgrd -c $CDS_ROOT/share/license/license.dat'" into .bashrc or csh.cshrc file,then enter the word "lmli" in the prompt to run license.dat.ok,now enter icfb& and work. Added...
