Abstract
A system is disclosed for enabling a user to specify a trigger condition of a signal or bus by enabling the user to graphically select the signal or bus from a hierarchically arranged list of signal or bus names. The user may make this selection from a graphical user interface of a signal measurement system. The user also graphically selects the signal trigger condition. A trigger-specification element identifying the trigger condition is visually associated with a displayed name of the first signal or bus. The user may select the signal trigger condition of the first signal or bus by selecting the first trigger-specification element. The signal measurement system may be a logic analyzer. The hierarchically arranged list may be vertically aligned and each signal or bus name may be visually associated with one of a first group of trigger-specification elements by horizontal alignment. Each of the first group of trigger-specification elements enables the user to choose from a group of trigger condition choices consisting of any one of: rising-edge, falling-edge, either-edge, low-level, high-level, don't care, bus, positive pulse, and negative pulse. Each of the first group of trigger-specification elements may be associated with a trigger condition that occurs at a first point in time. The system further may enable a user to specify a second trigger condition of the first signal or bus by selecting from a second group of trigger-specification elements that are visually associated with the names of the plurality of signals or buses. Each of the second group of trigger-specification elements may be associated with a trigger condition that occurs at a second point in time. The second group of trigger-specification elements may be displayed to the right of the first group of trigger-specification elements. The second period of time occurs later than the first period of time.
