Errors and warnings

Errors issued by the SDF annotator while loading the design prevent the simulation from continuing, whereas warnings do not. Use the -sdfnoerror option with vsim to change SDF errors to warnings so that the simulation can continue. Warning messages can be suppressed by using vsim with either the -sdfnowarn or +nosdfwarn options.

Another option is to use the SDF tab from the Load Design dialog box (shown above). Select Disable SDF warnings (-sdfnowarn, or +nosdfwarn) to disable warnings, or select Reduce SDF errors to warnings (-sdfnoerror) to change errors to warnings.

See "Troubleshooting" for more information on errors and warnings, and how to avoid them.
