Assigning a logical name to a design library
ModelSim SE User’s Manual
VHDL uses logical library names that can be mapped to ModelSim library directories. By
default, ModelSim can find libraries in your current directory (assuming they have the right
name), but for it to find libraries located elsewhere, you need to map a logical library name
to the pathname of the library.
You can use the GUI, a command, or a project to assign a logical name to a design library.
Library mappings with the GUI
To associate a logical name with a library, select the library in the workspace, right-click
and select Edit from the context menu. This brings up a dialog box that allows you to edit
the mapping.
The dialog box includes these options:
Library Mapping Name
The logical name of the library.
Library Pathname
The pathname to the library.
Library mapping from the command line
You can issue a command to set the mapping between a logical library name and a
directory; its form is:
vmap
You may invoke this command from either a UNIX/DOS prompt or from the command line
within ModelSim.
The vmap (CR-370) command adds the mapping to the library section of the modelsim.ini
file. You can also modify modelsim.ini manually by adding a mapping line. To do this, use
a text editor and add a line under the [Library] section heading using the syntax:
=
