3.3 Zooming, Scrolling, Measuring, and Searching

The Diagram window in BugHunter is the same timing diagram editor that is the basis of SynaptiCAD's WaveFormer Pro and Timing Diagrammer Pro products. Because of this, BugHunter users have access to many of the timing diagram editor drawing features. Some features of the Timing Diagram editor such as Timing Diagram Analysis, Reactive Test Bench Generation, and GigaWave require optional feature licenses. The timing diagram editor is described in the Timing Diagram Editors manual on-line help. There are several features that are particularly useful for viewing lengthy simulated signals. We have listed them here for your convenience.

Display Signal States by clicking in the time line

•Click in the timeline in the Diagram window to drop a temporary marker line that displays the numerical state of each signal.

Display Signal States using Markers

•Select the Marker button, then right click in the timing diagram to add a Marker. Hovering over a marker will show the state values of the signals at that time. To disable this feature, uncheck the Popup Display Signal States for Markers checkbox option in the Drawing Preferences dialog.

•To permanently display the state values beside a marker, double click on the marker and check the Display Signal States checkbox in the Marker Properties dialog.

Measuring Times

•The Time Button, with the black writing, displays the current position of the mouse cursor in the Diagram window. The Delta Button, with the blue writing, displays the difference between the mouse cursor and the delta mark (an upside-down, blue triangle) on the timeline above the Diagram window.

•To measure, left click on an edge (to select it and also move the delta mark), then move the mouse over another edge. The Delta button will display the difference between the mouse position and the blue mark.

Zooming in the Diagram window

•To zoom in and out quickly, hold down the <Shift> key while using the scroll wheel on your mouse.

<Shift> and mouse scroll wheel

•To zoom in over a visible section, drag and drop inside the Time Line.

•The zoom buttons are located on the diagram window button bar or under the View menu.

•The zoom in (+) and zoom out (-) center the zoom on the selected item, the blue delta mark, or the center of the diagram in that order.

•The zoom full (F) displays the entire timing diagram on the screen.

•The zoom range (R) opens a dialog that lets you specify the starting and ending times for the zoom.

Scrolling to a specific time or offset position:

•Press on either the Time or the Delta button to open an edit box, and type in a time. The Time button (black) causes the diagram window to scroll to that exact time. The Delta button (blue) causes the diagram window to scroll that amount from its current position.

Search for a specific signal name, parameter name or string:

•Select one of the child windows in the program, then type into the Search box on the main window bar.

•If the Diagram window is selected, then it will search for signal names.

•If a waveform edge is selected in Waveform window, then it will search for a signal value that matches the search string. The search will begin with the signal and edge that is selected and continue from left to right and down the page until a match is found.

•If the Parameter window is selected, then it will search for parameter names.
