After running the linter, the tool will bring up a new tab with the results.
Figure 1. Linter
The output will have a Rule ID, the RTL name of the signal or port that has the problem, the hierarchy where this is found, and a message and file name of where the potential problem is. In the previous figure, there is a port called “in3” in test.v, that is never used.
Note: The RTL linter will not update if the RTL has changed
and been saved. To see the new results after a change in RTL, the linter will need to be
re-run.
