Adding Lib in Model Sim

[Altera_Forum]

Hello, I am using sfixed data type in my vhdl code. (using ieee_proposed) When I try to compile the code in model sim, it gives me an error. Library ieee_proposed not found. Can anyone tell me how to add library in modelsim. 

 Similary, I am also using a matrix package which contains typical matrix function. I also want to include it in model sim as lib...

What version of modelsim are you using. Any version 10.1+ have the fixed point packages compiled into the ieee library (because it is part of VHDL 2008).  

 but as a reference for library etc in modelsim - from the command line/.do file   # create the library vlib my_library # compile files into a library vcom -work my_library my_vhdl_file.vhd # or if you have some compiled files elsewhere vmap my_library <some path>
