coregen on webpack 8.1

I have generated a DP ram core in webpack 8.1, and it creates the VHD files and templates. When I synthesize a file that instantiates a cor component it creates a 'black box' as I believe it should. When I try t implement the file, however, it complains" ERROR:NgdBuild:604 - logical block 'DPRAM' with type 'wrapped_dpram' coul not be resolved. A pin name misspelling can cause this, a missing edif o ngc file, or the misspelling of a type name. Symbol 'wrapped_dpram' is not supported in target 'spartan2'.



evidently because it can't find the .edn file (edif netlist) even thopug it's right there in the directory. Help!!!! Anybody know what's goin on?



BTW I am a relative newcomer to Webpack, although I have used previou versions successfully, but never with cores.

Have you set the macro path setting (Translate option) to where your edif or ngc file is located?

Isn't 'wrapped_dpram' a VHDL file? Include it in your project or cut & paste the code into your original file. if wrapped_dpram is the black box instantiation and the tool generated an .ngo or .edf file, John Adair's suggestion gets you going.
