Simulation and Verification

[lamonnis]

Hello,

I have a ML507 (V5FX70T) Evaluation board and I try to implement HW co simulation. In my previous post, I did a HW co simulation with only LUTs in my design. Now, I want to make a HW co simulation with a DSP included in an entity. You can see the hierarchy in the attach file.

When I run the simulation, I have the following error :

+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

INFO:HWCoSim - Implementing hardware co-simulation top-level through NGDBuild, MAP and PAR
ERROR:HWCoSim - Program 'xflow' reported the following errors:

   could not be resolved. A pin name misspelling can cause this, a missing edif
   or ngc file, case mismatch between the block name and the edif or ngc file
   name, or the misspelling of a type name. Symbol 'MULTIPLIEUR' is not

HDL wrapper and bitstream generation process failed.

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

So I think the error is concerning the instance U0 in the VHD generated by Coregen (instanciation of wrapped_Multiplieur).

I regenerated the Coregen, I imported ngc, vhd etc without success... but I can make HW cosimulation if I declare a bloc without Coregen in it (I_COMPTEUR for example in my design).

Perhaps anyone will have a good idea to help me !!!

Thanks a lot :)

MULTIPLIER was misspelled,

The tools do not speak French...

C'est domage, mais c'est le verite....

Hello,

Although I am french, I can understand English :)

That I don't understand is why a normal NGDbuild, MAP and PAR and simulation without HW co simulation work perfectly and why I have the problem with HW co-sim...

thanks

PS : Austin, LA vérité :)

Hello,

The problem is resolved by copying NGC sources directly in the project directory (same level than project.xise). Xflow doesn't use the same processes than a normal implementation where you can specify macro path.

perhaps it will be better supported in next releases.

That was not a french problem ;-)

How can you add ngc files if you are using fuse with command line?  I see the same error as described previously, but there is no .xise file when using command line.

Thanks.
