[COMPILE] Error: DSP Builder

[Altera_Forum]

Hi again! 

 I get an error when tying to compile with the flag -c: aoc -v -c cluster_k.cl  then: Internal Error: DSP Builder for Intel(R) FPGAs - Advanced Blockset Internal Restriction: 'm_startVec.size() > 0' in commonBackend::EnumerateLatencyConstraints::Private::beginSetIteration at p4/ip/aion/src/mip_common/latency_constraint_iterator.cpp:268.  Error: DSP Builder for Intel(R) FPGAs - Advanced Blockset Internal Restriction: 'm_startVec.size() > 0' in commonBackend::EnumerateLatencyConstraints::Private::beginSetIteration at p4/ip/aion/src/mip_common/latency_constraint_iterator.cpp:268.   the line that is causing this error is: b2 = ceil(components * tolerance);  components is an integer that is incremented through a loop, tolerance is a constant double. Whats the problem with the above line? (Also b2 is integer)  Thanks in advance

This looks like a bug in the compiler. Try the latest version of Quartus, v17.1. If you still got the same error, open a support ticket with Altera and report it.

Thanks HRZ :cool:

Excuse me, could you tell me how to open a support ticket with Altera? I met a same question whether Quartus 16.0 or 17.0 can solve the error.  

Thank you very much!
