The Libraries panel
shows the default and user-created HDL libraries for the project.
The files in the Libraries panel are used to compile the HDL source
files during synthesis. The following libraries are available:
Work Library - This
library appears by default and displays all HDL source files, CORE Generator™ cores,
and Architecture Wizard IP source files that are part of the design. After you
add a source file to the project, the ISE® software places the
source file in the work library by default.
Verilog Library - This library appears by default.
VHDL Library - You
can create a VHDL library to manage and store user-created VHDL libraries.
VHDL libraries are a collection of VHDL package files that define
custom HDL components not found in IEEE libraries. For more information
about creating and managing VHDL libraries, see Working with
VHDL Libraries.
Note The Libraries Panel toolbar provides convenient access
to frequently used Source menu commands. For more information, see Project Navigator Toolbars.
