ERROR:NgdBuild:604

Hi People ,

I am using a custom BRAM , but it is not getting synthesised , it keeps giving the error that ERROR:NgdBuild:604 - logical block 'my_transmitter_0/my_transmitter_0/dpram0' with type 'custom_bram_0' 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 'custom_bram_0' is not supported in target 'virtex2p'.

custom BRAM generated using ----> Xilinx Core Generator Xilinx ISE functional simulation -----> completed successfully Xilinx EDK BFM simulation -----> completed successfully Netlist ------> completed successully Bit Stream Generation --------> FAILURE

There has been traffic on this groups regarding the problem that I am facing, but none of the solutions that have been proposed are working in my case.

I have designed a OPB Master Slave Peripheral , in which I have used a Dual Port RAM generated by XilinxCoreGenerator. I name this core custom_bram.The following files are generated

1)custom_bram.asy 2)custom_bram.edn 3)custom_bram.sym 4)custom_bram.v 5)custom_bram.veo 6)custom_bram.vhd 7)custom_bram.vho 8)custom_bram.xco 9)custom_bram_flist.txt

I copied custom_bram.vhd into my user directory and instantiated it as a component in the main module.

Things that I have tried:

1) custom_bram uses an entity called XilinxCoreLib.blkmemdp_v6_3 defined in the library XilinxCoreLib . I copied all the related files from the blkmemdp_v6_3 into the pcores/hdl/vhdl directory.

2) i copied the custom_bram.edn file generated into a directory called /pcores/netlist and in the my_transmitter_0.mpd file made an entry specifying that OPTIONS STYLE = MIX.

3) In the instantiation of the custom_bram i have tried my_transmitter_v1_00_0.custom_bram ( as suggested in one of the posts on this group)

4) I am using 4 block rams in this designs ... In of the documents that I read , it was stated that you cannot make multiple instantiations of the same module, so i made 4 copies of the custom_bram , renamed them and referred to each only once

None of these have worked .... Any ideas ? :)

Thanks Venu
