Error -61499 in FPGA "An error occured"

Question

Hello,
I'm using Labview 2012 DS2 with FPGA module 12.0.0 and Xilings 13.4
When trying to complie my project, at the end I get this error: (the project was complied succesfully many times before, all I changed is control's default value and since then I get this error)
Error -61499 occurred at niFpgaCompileWorker_AnalyzeTimingViolations.vi<-niFpgaCompileWorker_AnalyzeTimingPaths.vi<-niFpgaCompileWorker_CheckForErrors.vi<-niFpgaCompileWorker_JobComplete.vi<-niFpgaCompile_Worker.vi:1
Possible reason(s):
LabVIEW FPGA:  An internal software error in the LabVIEW FPGA Module has occurred.  Please contact National Instruments technical support at ni.com/support.
Additional Information: Traceback (most recent call last):
  File "./objects/lvfpga_dist/win32U/i386/msvc90/release/root\resource\RVI\TimingViolation\scripts\niFpgaTimingViolationMain.py", line 280, in <module>
NameError: name 'constraintDict' is not defined
Return Code:1
Could anyone help me?

Answer 1

Dear Przemek,
 This might be one of the issues our R&D department is currently investigating. Could you please provide the following details?
What is the FPGA target yo're compiling for?
What is the resource utilisation of the bitfile? (an estimate will do)
Are there any derived clocks created?
Is there any 3rd party VHDL in the code?
As for the troubleshooting part, I'd recomend to try out the following:
Reduce te amount of controls and indicators on the front panel, especially large ones like arrays.
Try mass compiling the FPGA VI before compilation to test for corrption.
Modify some compiler settings on the bitfile creation. (see the attached screenshot). Try optimizing for area, and increase effort levels.
Please get back to me with the results.
