Implementation

[jar]

Hi,

I am trying to build a ofdm system using simulink and ISE. After generating the pcores from Simulink using system generator and exporting to EDK, I run synthesis, translate and map. It completes upto gobal optimization in map stage and then shows two errors

I searched some answer records and found that it can be rectified by manually editing the EDIF. I generated the EDIF file from the ngc file of the pcore using ngc2edif command and made the necessary changes (just changed the integer value of one property from 0 to 1 as the answer record suggested).

Now how am I to generate the ngc file from edif file. I tried using the ngcbuild but it fails saying that one particular line in the edif file exceeds the 256 component name limit specified by the EDIF standards.

How am I proceed from this stage?

The reply suggested that I post the question in this implementation forum for further help. I will delete my post there. Is there any way other tahtn editing the EDIF file?

[brucey · Accepted solution]

You may try add constraint "INST INST_name DOA_REG=1" to your ucf file.

[jar]

Thanks, the problem was solved. But why does that problem arise in the first place?

[brucey]

Maybe you generate the core in previous version. Or there's inconsistence between synthesis tool and implenetation tool.Or the DRC rule is stricter in current version.

Thanks :)
