How to add a peripheral IP generated by Coregen to EDK?

Hi,

I'm trying to add an IP(FFT), generated by Coregen, to an EDK project.

I have created a new custom IP in EDK and added the vhdl code of FFT into
user_logic.vhd file, and imported it to the EDK project, but I got three
errors:

ERROR:NgdBuild:604 - logical block 'fft_ip_0/fft_ip_0/USER_LOGIC_I/fft/U3'
with
   type 'fft128' could not be resolved. A pin name misspelling can cause
this, a missing edif or ngc file, or the misspelling of a type name.
Symbol 'fft128' is not supported in target 'virtex2p'.

I don't know what exactly these errors mean. Can anyone help to resolve
these problems?

Hi,

you need to add the search path to the edif in ISE so that it can find the netlist.
