it gives following error

# Reading C:/altera/11.1/modelsim_ase/tcl/vsim/pref.tcl # Loading project voq_switch_2# ** Error: (vish-19) Failed to access library '220model' at "220model".# No such file or directory. (errno = ENOENT)# ** Error: (vish-19) Failed to access library '220model_ver' at "220model_ver".# No such file or directory. (errno = ENOENT)# ** Error: (vish-19) Failed to access library 'altera_lnsim_ver' at "altera_lnsim_ver".# No such file or directory. (errno = ENOENT)

also tell me how to compile the library

The libraries are *already* compiled. You have somehow managed to mess up your Modelsim environment.

Why is Modelsim trying to open the project voq_switch_2?

If you just start Modelsim and do not open any project, then the mapping to the Altera libraries should work just fine.

If you are opening a project file, you might be over-riding the defaults and that is the problem. Try creating a new project from scratch. Personally I use Tcl scripts and never see this type of issue.
