Hi all,
I have a few issues with how to use the BBD file. key words ISE 8.2, XPS 8.2, BBD file, CORE Generator
step1. I create a core using coregenerator, generate .ngc (netlist) file out of it. step2. I use the core as a submodule in my design .vhd which is Master/ Slave OPB. step 3. In the system->pcores->mydesign->data/ i create a .bbd file and put the .ngc file name into it step 4 In the system->pcores->mydesign-> i create a netlist folder and put the .ngc (of the generated core) file in it
now when i generate bitstream it gives me error in the Ngdbuild ============================================================= here is the error
........................ ERROR:NgdBuild:604 - logical block 'opb_master_ml300_camera_bridge_0/opb_master_ml300_camera_bridge_0/ user_fifo1 /block0' with type 'fifo_generator_v3_2' 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 'fifo_generator_v3_2' is not supported in target 'virtex2p'.

any ideas where i am going wrong. please ask me for more info if you think the info is not enough.
with warm regards to the design community. chakra.
