Waveform simulation vopt error - Waveform simulation vopt error Hello i just recently installed the Quartus Prime Lite edition version 22.1.1 and i am trying to use the waveform editor. When i try to run the simulation i get the following error: Error (suppressible): (vsim-12110) All optimizations are disabled because the -novopt option is in effect. This will cause your simulation to run very slowly. If you are using this switch to preserve visibility for Debug or PLI features, please see the User's Manual section on Preserving Object Visibility with vopt. -novopt option is now deprecated and will be removed in future releases. # Error loading design I am using the default settings: vsim -novopt -c -t 1ps -L cyclonev_ver -L altera_ver -L altera_mf_ver -L 220model_ver -L sgate_ver -L altera_lnsim_ver work.and_block_vlg_vec_tst changing -novopt to -vopt removes the error but the simulation outputs doesn't seem to make sense, for example a simple AND block with both inputs set to 1 produces a constant 0 Can anyone help me resolve this? Thank you Replies: Re: Waveform simulation vopt error Hello, I’m glad that your problem has been solved, I now transition this thread to community support.
