Supported Search Types

When analyzing the captured data, the ability to search forward and backward for specific pattern matches or packet values, is indispensable. DigiView provides a general search type for pattern matches, several search types for specific signal types (such as I2C) and a Search Manager to quickly perform multiple searches and change criteria.

• Pattern Match - Search any combination of Boolean and Bus signals for patterns and duration of patterns.
• Asynchronous Serial Signal Search - Search any Asynchronous signal using a sequence of "Skip then Match" stages. Each stage can also contain a sequence of data to match or packet errors (i.e. Framing Error etc).
• Synchronous Serial Signal Search - Search any Synchronous signal using a sequence of "Skip then Match" stages. Each stage can also contain a sequence of data to match or packet termination errors (when signal uses an Enable qualifier).
• I2C Serial Signal Search - Search any I2C signal to match a combination of I2C protocol elements.
• State Signal Search- Search any State signal using a sequence of "Skip then Match" stages. Each stage can also contain a sequence of data to match.

Properties common to all Search Types

Search Name - Use the Name field to describe the search. This descriptor will be displayed in the Search Manager Windows and in the Global Search selection box.

From - Where to begin Searching. The 'search from' selection determines where the search starts from; the current center of screen or the current marker location. Since the marker is placed at the center of the screen after the first search match, these are often the same during consecutive searches. The main difference occurs during the first search or between searches if you scroll the screen.

Set Marker - Mark the match point. The marker selection determines which marker is used to show the search match. You must select one. Whenever the search matches, the selected marker is placed at the match point and then centered in the searched window.

Search Button - Performs the search. Use the Search button to test the settings you have just entered for this search. Right-Click to search forward from the current time of the marker. Left-Click to search backward from the current time of the marker. When you are satisfied with the search settings, you can close the search and use any search button in the application to continue searching.
