Zooming - changing the waveform display range

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

Using the Zoom menu

You can use the Wave window menu bar, or call up the Zoom menu by clicking the right mouse button (of a three-button mouse) in the waveform pane.

Note: The right mouse button of a two-button mouse will not open the Zoom menu. It will, however, allow you to create a zoom area by dragging left to right while holding down the button.

The Zoom menu options include:

• Zoom Full
  Redraws the display to show the entire simulation from time 0 to the current simulation time.
• 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 Last
  Restores the display to where it was before the last zoom operation.
• 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 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.
