US Patent:

6624830, Sep 23, 2003

Filed:

Oct 29, 1999

Appl. No.:

09/432840

Inventors:

Douglas J Beck - Colorado Springs CO
Michael S Backsen - Westcliffe CO
Douglas F Robison - Colorado Springs CO
John H Friedman - Colorado Springs CO

Assignee:

Agilent Technologies, Inc. - Palo Alto CA

International Classification:

G06F 314

US Classification:

345771, 345773, 345769, 345835, 345839

Abstract:

A system is disclosed for displaying one or more lists of signal or bus identifiers on a graphical user interface of a logic analyzer. One of the lists is visually associated with one name of a list of signal or bus names. The system enables a user to graphically select one or more desired identifiers of the one or more lists of signal or bus identifiers. The selection of an identifier in a list visually associated with a name assigns a signal or bus identified by that identifier with the name. The lists of signal or bus identifiers may be visually associated with the signal or bus names by horizontal alignment.

International Classification:

US Classification:

Abstract:

A logic analyzer integrates the capabilities of both textual and graphical description into a common environment, so that each can be used as needed, and in conjunction with the other. In an example embodiment a trigger specification can comprise many âstepsâ. A step can be conceptualized as an atomic segment of flow charting that involves or investigates a quantity or condition of interest. These steps may involve testing, and a decision concerning whether or not to trigger or whether or not to advance to a next step. A given step can be either textual or graphical. A GUI (Graphical User Interface, as in computer windows, and not to be confused with âgraphicalâ meaning âwaveform-likeâ) on a CRT screen in conjunction with a pointing device (e. g. , mouse) provides the presentation of the integrated textual and graphical (waveform-like) trigger specification steps.

Appl. No.:

Inventors:

Douglas Beck - Colorado Springs CO, US

John Friedman - Colorado Springs CO, US

International Classification:

G09G005/00

US Classification:

345/805000, 345/771000

Abstract:

Placement position errors for a selected marker within a logic analyzer trace are avoided by allowing the operator to click within the region occupied by a waveform of interest, detecting the subsequent direction of horizontal mouse motion and combining that with the marker's current location to determine which signal transition within that waveform of interest would be encountered next by the selected marker as it moves in the detected direction. The selected marker is then automatically placed at that location. A marker can be selected by clicking on its icon in advance, or automatically as part of the waveform selection by clicking sufficiently close to a cursor portion of the marker as it passes through the waveform. A number of further considerations come into play if such a system is to be convenient to use and intuitive.

Assignee:

Agilent Technologies, Inc. - Palo Alto CA

International Classification:

G06F 1125

US Classification:

714 39, 714 45

Abstract:

Waveform segment(s) of interest in the displayed logic analyzer trace can create the desire in an operator to re-define the trigger specification to be those segments. Those waveform segments are identified to the logic analyzer by drawing a ârubber bandâ box around them even as they are displayed as part of the trace. The analyzer is instructed to automatically create therefrom, by itself, the desired new trigger specification. It does this by inspecting the captured data corresponding to the contents of the box and creating a description of the associated signal(s) in terms of transitions and steady state conditions. These individual descriptions of activity are then assembled into a trigger specification according to certain rules. More than one box may be drawn. Multiple-boxes may be âstackedâ to include waveform segments separated vertically by intervening waveforms for other signals that are to be excluded.
