Zooming - changing the waveform display range

Zooming lets you change the simulation range in the waveform pane. You can zoom with either the context menu, toolbar buttons, mouse, keyboard, or commands.

Using the Zoom menu

You can use the Wave window menu bar, or call up the context menu by clicking the right mouse button in the waveform pane.

The Zoom menu options include:

• Zoom Area with Mouse Button 1
  Use mouse button 1 to create a zoom area. Position the mouse cursor to the left side of the desired zoom interval, press mouse button 1 and drag to the right. Release when the box has expanded to the right side of the desired zoom interval.
• Zoom In
  Zooms in by a factor of two, increasing the resolution and decreasing the visible range horizontally.
• Zoom Out
  Zooms out by a factor of two, decreasing the resolution and increasing the visible range horizontally.
• Zoom Full
  Redraws the display to show the entire simulation from time 0 to the current simulation time.
• Zoom Last
  Restores the display to where it was before the last zoom operation.
• Zoom Range
  Brings up a dialog box that allows you to enter the beginning and ending times for a range of time units to be displayed.

Zooming with toolbar buttons

These zoom buttons are available on the toolbar:

Zoom in 2x zoom in by a factor of two from the current view	Zoom area use the cursor to outline a zoom area
Zoom out 2x zoom out by a factor of two from current view	Zoom Full zoom out to view the full range of the simulation from time 0 to the current time

Zooming with the mouse

To zoom with the mouse, position the mouse cursor to the left side of the desired zoom interval, press the middle mouse button (three-button mouse), or <Ctrl>+left mouse button (two-button mouse), and while continuing to press, drag to the right and then release at the right side of the desired zoom interval.
