  • Patent number: 9858374
    Abstract: An improved approach is provided to displaying waveform data, where a schematic and corresponding waveform data can be displayed directly on a schematic of an electronic circuit. By providing both the schematic and waveform results in a same display, circuit designers and verification engineers are given more control over their working environments and can more efficiently utilize available data including the schematic and the waveform data. Furthermore, results can be pinned to a relevant net to which those results correspond providing circuit designers and verification engineers with an ability to view only the available data they wish to view, and to do so in a context of the electronic circuit itself on the schematic.
