Analyzing Simulation Results: A Comprehensive Overview
In Xpedition AMS, the Waveform Analyzer plays a crucial role in viewing and analyzing simulation results. This powerful tool provides a dynamic graphical display of mixed-signal simulation data, allowing users to observe and investigate various aspects such as signal transitions, timing effects, and what-if analyses. By utilizing the Waveform Analyzer, users can gain valuable insights into their simulations and make informed decisions based on the obtained results.
To access the Waveform Analyzer, simply select the Simulation > Waveform Analyzer menu item. Upon opening the Waveform Analyzer, users are presented with graph windows, tabbed workspaces, and a Waveform List that organizes databases in a hierarchical or flat list format. One notable feature is the ability to save the current waveform file, along with the window display, for future reference and analysis.
The Waveform Analyzer offers a range of capabilities to enhance the analysis experience. Users can zoom in and out of waveforms, scroll along the horizontal axis, and measure waveforms between transition points using cursors. Waveforms can be easily dragged and dropped into graph windows, allowing for easy comparison and overlaying of multiple waveforms. The viewing area and scale of the graph can be adjusted to focus on specific details. Furthermore, users can print displayed waveforms, copy them to the clipboard for use in other documents, or save them as JPEG files.
The graph window serves as the primary display area within the Waveform Analyzer. It provides a visual representation of plotted waveforms and allows users to interact with and analyze the data effectively. Basic actions, such as plotting, moving, copying, and zooming in and out of waveforms, can be performed within the graph window.
Xpedition AMS saves simulation results as waveform database files with the extension ".wdb". Additionally, users have the option to save an entire graph window as a formatted file with the extension ".swd", capturing the operations performed and allowing for easy recreation of the window at a later time.
The Waveform Analyzer also offers advanced operations to further enhance waveform analysis. One notable feature is waveform measurements. Users can utilize waveform cursors to track values along a waveform, measure differences between points, and perform in-depth analysis. Cursors can be added, locked together, and deleted as needed. X-Y Markers are another powerful tool that displays delta-X and delta-Y values between two points on one or two waveforms. Users can move the anchors of X-Y Markers, copy values to the clipboard, show or hide marker values, and restore hidden markers.
The Waveform Analyzer in Xpedition AMS provides a comprehensive platform for analyzing simulation results. Its dynamic graphical display, extensive measurement capabilities, and user-friendly interface empower users to gain valuable insights from their simulations. By leveraging the Waveform Analyzer's features and tools, engineers and researchers can make informed decisions and drive successful design outcomes.
