Hello,i'm doing a design which uses sfixed, so it needs the IEEE_PROPOSED library in the fixed_pkg_c.vhdl file exactly, so i've run into problems by generating a Testbench for my project that the modelsim complains, of not having that library: ** Error: C:/Users/Alfonso/Desktop/PFC/altera/fixed_pkg_c.vhdl(22): Library ieee_proposed not found.# ** Error: C:/Users/Alfonso/Desktop/PFC/altera/fixed_pkg_c.vhdl(23): (vcom-1136) Unknown identifier "IEEE_PROPOSED".# ** Error: C:/Users/Alfonso/Desktop/PFC/altera/fixed_pkg_c.vhdl(28): VHDL Compiler exiting# ** Error: E:/altera/11.1sp2/modelsim_ase/win32aloem/vcom failed. while the compilation ends succesfully. I think is something related to libraries for some google i've done. Thank you Alfonso.
you could just follow those commands. They will solve your problem.Those commands need to be typed into the modelsim command window. Its nothing to do with managing C libraries.
navigate (in modelsim) to the directory where you have the ieee_proposed codevlib ieee_proposed vlib work vmap work ieee_proposed vcom <vhdl files .vhd> # do this for all the files navigate back to your project vmap ieee_proposed directory/of/ieee_proposed
