Creating a Plot-On-Schematic

After Twin Builder generates a solution, you can analyze your solution data by creating a 2D report that displays the relationship between a design’s values and the corresponding analysis results. One convenient way to generate a 2D report is to create a Plot-On-Schematic, which generates a standard 2D rectangular plot associated with the selected component, displaying the plot alongside the component in the Schematic editor.

You can create a plot-on-schematic using either Probe, Quick Probe, or Probe Selection as follows:

Probe Command

  1. Right-click the desired component and select Probe.

    A list of quantities that can be plotted, such as voltage across the component, appears. The list of quantities is determined by the Probe Quantities & Signals settings on the Twin Builder tab of the Schematic Options dialog box, and any output that is selected in the Defined Outputs set in the Output dialog box. By default, the probe settings for the Twin Builder schematic have output quantities turned-on.

  2. Select the quantity you want to plot from the list. The probed quantity is plotted and placed on the schematic next to the selected component.
    • The plot is associated with the component so that, as the component moves, the plot moves with it.
    • The plot can also be relocated directly by selecting and dragging it.
    • The plot can also be resized by dragging any of its handles.
    • Text is resized with the plot.
    • The created plot also appears in the Results folder in the Project tree. Double-click the plot listing in the tree to open it in a new window.
      Note:

      If you change the display type to Data Table, the on-sheet plot will go blank (data tables cannot be shown on the schematic). Instead, a separate Data Table dialog box appears.

    • Each component/net/port can have only one on-sheet plot associated with it. You can have multiple plots on the same schematic, but only one such plot for each component.
    • If you double-click a plot in the schematic, the plot becomes fully editable. You can move the legend bar around, change the color of traces, change scaling for X- and Y-axis – every operation you can normally perform in a regular plot window. You can also add plot markers. For more information see Modifying Reports. When you click outside of the plot, it reverts back to being another schematic object.
    • Plots are dynamically updated when you modify an analysis.

Quick Probe Command

Quick Probe command operates similarly to Probe. However, instead of offering a list of choices to plot, it plots the first quantity for the selected component or net as defined in the list of quantities for the Probe command. Derivative quantities (for example, dV) are not available for the Quick Probe command.

Probe Selection Command

The Schematic > Probe Selection command operates like the Quick Probe command: plotting the first quantity for the selected component or net.
