Quartus Prime University Program VWF Functional Simulation Error

[Kefayet]

I am trying to simulate a 1 bit 2-to-1 MUX waveforms in Simulation Waveform Editor. But while running the simulation I am getting the following error. Expecting any help urgently. Thank you

Hi Kefayet,

Could you provide the .qar design file to me and steps taken to reproduce the error? Can attach it here or private message me if it is confidential.

Thanks,

Regards

I have almost solved the previous errors, now I have the following errors.
I am sorry I am not familiar to the .qar file type but I have attached the VHDL file here. 
Thank you

Please find the code here

Hi Kefayet,

This issue is probably due to open the specified file in read mode.

You have to validate that the path exists and you have the correct permissions in the directory. I can see you have space in your path "simulation singlebit_MUX2.vho".

Change to other name or put "_" or combine the name to simulationSinglebit_MUX2.vho.

Thanks,

Regards
