Benefits of technology

Enables effective visual correlation between measured and simulated waveforms by facilitating the conversion of picture files into X, Y plot format, reducing the need for additional lab measurements and improving data comparison efficiency.

Problems solved by technology

While some oscilloscopes allow for some limited XY data to be saved of a single trace, often this is not possible, for example, for XY data of a picture of an eye or eye diagram.
Therefore, a problem exists in getting a good visual of the correlation between simulated eye diagrams, and measured eye diagrams.

Embodiment Construction

[0012] Having reference now to the drawings, in FIGS. 1A, and 1B, there is shown a computer or data processing system generally designated by the reference character 100 for implementing picture format conversion to X, Y plot in accordance with the preferred embodiment. As shown in FIG. 1A, computer system 100 includes a central processor unit (CPU) 102, a read only memory 103, a random access memory 104, a display adapter 106 coupled to a display 108. CPU 102 is connected to a user interface (UI) adapter 110 connected to a pointer device and keyboard 112. CPU 102 is connected to an input / output (10) adapter 114 connected to a direct access storage device (DASD) 116 and a tape unit 118. CPU 102 is connected to a communications adapter 120 providing a communications function.

[0013] Computer system 100 is shown in simplified form sufficient for understanding the present invention. The illustrated computer system 100 is not intended to imply architectural or functional limitations. Th...

Abstract

A method, apparatus and computer program product are provided for implementing picture format conversion to X, Y plot for waveform comparisons. A picture file and user selected X, Y boundaries are received. Non-white pixels of the picture file between the user selected X, Y boundaries are converted to X, Y coordinate values in a selected format. The converted X, Y coordinate values are plotted.

Description

FIELD OF THE INVENTION [0001] The present invention relates generally to the data processing field, and more particularly, relates to a method, apparatus and computer program product for implementing picture format conversion to X, Y plot for waveform comparisons. DESCRIPTION OF THE RELATED ART [0002] Pictures of waveforms from oscilloscopes are often saved as a file in a picture format, such as BMP, GIF, JPEG, PNG, and the like. Often times, after taking a picture, some other data is needed that you may have forgotten to measure or did not need to measure at that point in time, such as slew rates, eye openings, cycle times, and the like. In order to get accurate measurements, it is usually required that you spend another day or more in the lab probing up a system, getting the system running, and taking needed measurements. [0003] It is very useful to be able to overlay a picture of a waveform from actual hardware, and from a simulation of the hardware under test in order to visuall...
