The menu selection Project → Add Copy of Source has
also been enhanced to copy cores from other directories and their
associated files. This includes the XCO, SYM, VHO, VEO, EDN,
and MIF files for each core.

New HDL flow improvements.
Design Flow
The CORE Generator System produces an Electronic Data
Interchange Format (EDIF) netlist, and may also produce a schematic
symbol, and/or a Verilog Output (VEO) with a Verilog (V) wrapper
file, or VHDL Output (VHO) template file with a VHDL (VHD)
wrapper file. The Electronic Data Netlist (EDN) file contains the
information for implementing the module.
The schematic allows you to integrate the CORE Generator module
into an ECS schematic. Finally, the VEO and VHO template files
contain code that can be used as a model to instantiate a CORE
Generator module in a Verilog or VHDL design so that it can be
simulated and integrated into a design.
Note Verilog and VHDL wrapper files are used to pass information to
the Xilinx CoreLib Simulation models. VHDL wrapper files are used
only by ISE during simulation. Only Verilog wrapper files are used
by ISE during Verilog synthesis to provide Port direction information
to the Synthesizer.
You can download new cores from the Xilinx Web site and add these
cores to the CORE Generator. The URL for downloading cores is
http://www.xilinx.com/ipcenter. Check this Web site to verify that
you have the latest version of each core and core data sheet.
