Table View Windows
Table views present the data as a list of numbers (tabular form). Table windows can be created by using the Feature Window button on the Top Toolbar, by using the local menu of a Boolean or Bus signal in Waveform Views or by using the Main Menu (Menu-> Window-> New-> Tabular View). Table creation selections in the Main Menu and Feature Window lists are only available after creating a Signal Definition.
Any signal type can be displayed in Tables. However, decoded signals will be displayed in their raw channel values. To see the decoded values of these signals in a tabular view see List View Windows.
To create a new Table Window, select the "Open Feature Window" button from the main toolbar, then select the name of a defined Boolean or Bus signal from the Tabular View menu item. If you select any other type of signal, a List View will be created instead. Only the Signal Definitions you create for the project will be listed on the Tabular View.
This mode compresses out the 'dead-time' between transitions, packing a lot more information into a screen of table data. Each line of data in the table contains the timestamp and the data. The time between lines varies and corresponds to the length of time the previous sample was stable. In this mode, a 40 line table contains 40 transitions. In linear (non-compressed) mode, it would contain 40 SAMPLES with perhaps NO transitions. If multiple signals are added to the table, the compression algorithm takes ALL signals in to account. A new line is shown any time ANY of the signals change state. Nothing is lost or thrown away. We simply compress out the redundant information, making the table hold more significant data. You can switch between compressed and linear views with a single click at any time.
Although compressed mode is the most efficient way to display a signal in tabular form, some people have trouble visualizing the non-linear, compressed time. You can Link a compressed table with other non-compressed tables or with waveform displays to correlate the data to a linear view. This allows BOTH an efficient table view and a linear 'in-context' view.
The included '8051.dat' example demonstrates this well. The OE signal in that example is spread across about 1.4 Million samples but can be displayed in less than 20 table lines when compression is enabled. When this table is linked to a waveform view, scrolling through this small table quickly scrolls the waveform to each significant event in the OE signal. This is a real-world example captured from a real embedded system.
Delta vs. Linear time
Regardless of the display mode( normal, compressed or down-sampled), you can display the time field in absolute or delta time. Absolute is the actual timestamp of the sample (relative to trigger). DELTA mode shows the time between table lines. This is most useful in compressed mode where it tells you the time between transitions. In normal and down-sampled modes, it simply tells you the sample rate( since the time between each line is constant).
The table's menu offers several useful functions such as navigating to a reference point, adding additional signals, configuring the time and so forth. To activate the menu for a specific signal from within the table, right-click in the signals' column. Examples of these menus are displayed below.
