# Removing modelsim error

I am trying to simulate a simple inverter in verilog using modelsim 10.7 version. While compiling the code I am getting the -novopt error (error code 12110). As per user manual page 80; the -novopt argument is to be removed from vlog, vcom and vsim commands and from voptflow variable in the modelsim.ini file.

To remove the error, I set the voptflow variable to '0!' but could no find this argument for vlog, vcom and vsim commands. Pls. tell me how to go about solving the issue so that I dont get the error. I am attaching a snapshot of the error popup and my modelsim.ini file here.

• Why are you using -novopt in the first place? – Dave Tweed Jul 11 '19 at 12:44
• Don't remember the GUI flow, but from command line you should be able to compile using vlog -work work file_name.v and then run vsim work.file_name for simulations. – rvkrysh Jul 12 '19 at 1:17
