Library in Protected Region using Questasim

I am getting this error when I try to simulate my design using Questasim:

** Error: C:/quartuspro/quartus/eda/sim_lib/mentor/cyclone10gx_atoms_ncrypt.v(36): in protected region
# Optimization failed
# Error loading design

 

Anyone know what is causing this?

Hi @Nitin1 

 

Have you compile the simulation libraries before you simulate your design? 

You may checkout the User Guide below on how-to simulate Intel FPGA Designs using third party simulator tools.

Hi @Nitin1 

 

Have you try to simulate in our Modelsim Intel FPGA Edition?

See if the issue persists.  

Share me the simulation log file and the simulation script so I can investigate further.

Hi Richard,

I tried Model sim Intel Starter FPGA edition but get different errors. I have attached simulation files.

Hi Richard,

Is it possible to get a temporary license for Intel Modelsim Intel FPGA Edition (not Starter edition) to see if the problem goes away?

Hi @Nitin1 

 

Sorry, we do not provide temporary license here. You may need to contact your distributor FAE if you have one dedicated to your account/company.

Hi @Nitin1 ,

 

I don't really get much from the .zip file. 

What types of error that you get when simulate using the Modelsim Intel Starter FPGA edition?

Does it pass the previous error that occurred in Questasim?

Hi @Nitin1 

 

May I know what types of error that you get when simulate using the Modelsim Intel Starter FPGA edition?

Does it pass the previous error that occurred in Questasim?

Could you help to share the design files, testbench, script as well so I can look into this further?

Richard Tan
