modelsim将波形文件保存下来却不打开图形界面

vsim -c -do sim.tcl -l sim.log

波形怎么保存啊，我想把波形保存下来，但不显示，想看那个信号时在加上，不然信号全部出来了太乱了

在do文件里写
add wave -r *
run -all
exit

-------------------------------------------------------

1. vsim -c -do run.do -l vsim.log -wlf vsim.wlf
2. the contents of run.do:
    log -r /*
    run -all
    exit -f

you can see the vsim.wlf file in your simulation directory. Next time you can load vsim.wlf into modelsim, then you can look the waveforms of all signals.
