Error: The -novopt option has no effect on this product - Error: The -novopt option has no effect on this product I first downloaded the latest version of Quartus Prime Lite edition, after runing the simulation wave form editor, I got this error Error (suppressible): (vsim-12110) The -novopt option has no effect on this product. -novopt option is now deprecated and will be removed in future releases. # Error loading design under **** Running the ModelSim simulation **** Then I deleted this version and downloaded version 20.1 and I got this error again. I didn't find any similar case on the internet. by the way, *I used the block diagram first and t he compilation was successful then I run the simulation wave form editor. *My modelSim version is also 20.1. *The program couldn't find the path to ModelSim at first, so I changed the modelsim path from Tools -> Options -> EDAtools, the path is changed to C:\intelFPGA\20.1\modelsim_ase\win32aloem. *I am using a MacBook and have installed Quartus in BOOTCAMP. My project file is located in the Onedrive folder.

Replies: Re: Error: The -novopt option has no effect on this product Hello , i did this and the output doesn't come only shows x Replies: Re: Error: The -novopt option has no effect on this product Thank you so much !!! The problem is solved! Replies: Re: Error: The -novopt option has no effect on this product Hi, In the Simulation Waveform Editor, go to Simulation -> Simulation Settings. Next, delete -novopt to bypass the problem. Best Regards, Sheng p/s: If any answer from the community or Intel Support are helpful, please feel free to give best answer or rate 4/5 survey.
