DSP Builder Advances blockset sqrt block problem

Hello! I'm using DSP builder blockset and I have problem with SQRT prim block. I just cannot use two of this block! If I use more than one sqrt block in any subsystem (i tried to use it in one subsystem with, of course, different names) I will get that error: 

 

Error reported by S-function 'mip_control' in 'mixer/Control': 

Altera DSP Builder Advanced Internal Restriction: 'blockMap.find(fu->GetName()) == blockMap.end()' in d:/SJ/nightly/12.0/178/w64/p4/ip/aion/src/mip_common/hw_model_dup_remover.cpp:191.  

I google it and it said that this because illegal chars in the names, but I have double cheched this! I don't know what to do, help needed.

I can reproduce the problem. I don't think there's a work around unfortunately short of avoiding putting two sqrt blocks inside the same primitive subsystem hierarchy.

Thank you for the reply! 

But they are in the different subsystems! 

 

Here is the example.

I didn't say they can't be in the same subsystem. I said they can't be in the "same primitive subsystem hierarchy". Essentially this is everything below the SynthesisInfo block. 

 

The reason for this is that DSP Builder Advanced flattens all of the subsystems in this hierarchy before generating the HDL.

Ok. Do you have any suggestion? Maybe a bugreport, I don't know...

I've reported the issue but unfortunately it's still present in 12.1. Hopefully it will be fixed in 12.1sp1.
