Hi, there:
Is there anyway to merge the NGC cores from 3rd party vendors into my final NGC file? I found -read_cores YES only read in the NGC file for analysis...
Best Regards, Kelvin
XST -read_cores YES doesn't merge the NGC into the compiled file...

I think you have to instantiate your cores as black boxes for synthesis, and then integrate them into the design during the translate stage
You can run PAR and use the floorplanner to capture your new (bigger) NGC core. XAPP 422 has all the details.
That's the way I do it, but it may not be the only solution.

You can merge netlists together through ngcbuild (not ngdbuild). Ncgbuild would then merge all the netlist into a single ngc file. This was introduced in 6.2i.

yeah, that was the way i did it. but i think it is a good idea to give user the option to merge NGC files...i am glad ise-6.2 has implemented that.
