Making cursor measurements

Each cursor is displayed with a time box showing the precise simulation time at the bottom. When you have more than one cursor, each time box appears in a separate track at the bottom of the display. ModelSim also adds a delta measurement showing the time difference between two adjacent cursor positions.

If you click in the waveform display, the cursor closest to the mouse position is selected and then moved to the mouse position. Another way to position multiple cursors is to use the mouse in the time box tracks at the bottom of the display. Clicking anywhere in a track selects that cursor and brings it to the mouse position.

The cursors are designed to snap to the closest wave edge to the left on the waveform that the mouse pointer is positioned over. You can control the snap distance via the
Edit > Display Properties menu selection.

You can position a cursor without snapping by dragging in the area below the waveforms.

You can also move cursors to the next transition of a signal with these toolbar buttons:

Find Previous Transition locate the previous signal value change for the selected signal

Find Next Transition locate the next signal value change for the selected signal
