time cursors in the Wave window

When the Wave window is first drawn, there is one cursor in it at time zero.

Clicking anywhere in the waveform display brings that cursor to the mouse

location.

You can add additional cursors to the waveform pane with the

Cursor > Add Cursor

menu selection, or with the

Add Cursor

button on the toolbar.

The selected cursor is drawn as a solid line; all other cursors are

drawn with dotted lines.

Remove a cursor by selecting it and choosing using the

Cursor >

Delete Cursor

menu selection, or use the

Add Cursor

button on

the toolbar.

Finding a cursor

Choose a specific

cursor view with

Cursor > Goto

menu selection. The

cursor value (on the

Goto

list)

corresponds to the

simulation time of

that cursor.

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. VSIM also adds a delta measurement

showing the time difference between the two 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.
