Abstract
Improving on the waveform viewing technology can advantageously address the industry's need for speedup and capacity of existing solution. As described herein, making data manipulation local and bounded can facilitate tremendous speedup. The waveform viewer can process data on-demand where the user explicitly specifies signals and a desired window (i.e. range). Operations including, but not limited to, zoom, pan, scan, etc. on the waveform viewer can be sent to the waveform servers in the form of a query containing the visualization parameters (e.g. number of pixels), which in turn compute bitmaps (or other waveform images) that are sent back to be displayed.
