Such as ：vsim -c -l vsim.log -do ./YourDo.do -L ./work work.foo
Start emulating :
-c Option to vsim Working in commandline Pattern ;
-l The option is output log File to vsim.log;
-do The option is to start the simulation and run tcl Script files ;
-L The option is to specify the working logic library ;
work.foo It's simulated top level module.
