Simulator Not Starting

Hello,

 

I have been working on a simple testbench project, and I have now rebuilt the entire project a second time thiking I had corrupted it somehow, and am getting the exact same error messages as the last time. The first three or so times, the simulator starts perfectly, then after that I always get the same error that the "Simulation Engine failed to start". I understand this is a generic message, but the only preceeding error is absolutely unintelligible to me:

 

"Could not open the HDL type file std::endl"

 

This does not make any sense to me. The entire relevant section of TCL Console output is below:

Thanks for any help!

Re: Simulator Not Starting

Try to create a new project and move the files to run simulation. Looks to be a project corruption issue. I hope you are using a supported OS.
