How do I use a NGC file toanother ISE project.

Hi!

I got a IP core from the Xilinx .After System Generator and creat a lot of files include a ISE project file.

I open the ISE file and synthesis it create a NGC file. And then I create an another completely new ISE project.

My ploblem is that how could I use that NGC file as a black box and add to the new project. Because at the top_level file I must use the interface in the IP core. 

Thanks . I am sorry about my english level.

Hi,

 

Copy all the NGC in one directory, and there is an option at Ngdbuild "Macro Search Path", please give the NGC directory path near this option. Please check the screenshot attached.

 

Thanks

Use BoxType (BOX_TYPE) constraint on the IP core so that to skip synthesis on the core. Please check XST User Guide < http://www.xilinx.com/support/documentation/sw_manuals/xilinx12_2/xst.pdf > page no: 200 à explains the BOX_TYPE constraint.

Hi! Thank you very much. I have solved that ploblem.I copy the NGC file to the new project directory.

Next I write a wrapped file referencing the .v file.Then I instance the black box as the usual module.
