Comparescan User Guide
Comparescan Graphical User Interface
Button Bar
The Comparescan window button bar gives you quick access to the functions that you use most often. All of the button functions are also available on the menus.
The Comparescan window contains the following buttons:
Table 4-1 Comparescan Window Buttons
Run—Starts the comparison that you have defined on the Compare Options form. See “Compare Options Form” on page 40 for more information on this form. This button has the same functionality as the
Tools—Run Comparison menu option.
Stop—Aborts the currently running comparison. This button has the same functionality as the Tools—Stop Comparison menu option.
If you click this button, you cannot resume the aborted comparison. However, you can restart the aborted comparison from the beginning by clicking the Run button.
Pause—Pauses the currently running comparison. This button has the same functionality as the Tools—Pause Comparison menu option.
Continue—Resumes a paused comparison, starting at the time at which you paused it. This button has the same functionality as the
Tools—Continue Comparison menu option.
Options—Opens the Compare Options form. See “Compare Options Form” on page 40 for a description of this form. This button has the same functionality as the Tools—Compare Options menu option.
H-View—Lists the compare errors in the Comparescan window hierarchically, by module name. This button has the same functionality as the View—View by Hierarchy menu option.
TimeView—Lists the compare errors for your comparison in the Comparescan window in simulation time order. This button has the same functionality as the View—View by Time menu option.

Comparescan Graphical User Interface
Table 4-1 Comparescan Window Buttons
Prev—Displays the previous error in the error list in the Comparescan window and in any open Signalscan Waves window. This button has the same functionality as the View—Previous Error menu option.
Next—Displays the next error in the error list in the Comparescan
Window and in any open Signalscan Waves window. This button has the same functionality as the View—Next Error menu option.
In addition to the above buttons, the Comparescan window’s button bar also contains a run-time animation. This animation is active when Comparescan is working on a comparison, and is a good indicator of how hard the program is working. Each time the program completes a comparison, the Comparescan window displays a Summary message, and the run-time animation stops moving.
