Analyzing Results

Advanced Design System uses datasets to store the simulation information you generate when analyzing designs. You can display this information for analysis using the Data Display window. A Data Display window can also be used to display data imported from other sources.

In a Data Display window you can:

• Display data in a variety of plots and formats
• Use markers to read specific data points on traces
• Use equations to perform operations on data
• Annotate results using text and illustrations
  Once a simulation is complete, the data is displayed automatically if you did one of the following (a blank Data Display window is opened if you did none of them):
• Specified a dataset and display before simulation
• Used a schematic template for an Analog/RF simulation
• Specified Rectangular in the Plot parameter in a sink for a Signal Processing simulation

Creating Data Displays

The basic process of creating a data display is as illustrated:

1. Choose a plot type for the display
2. Choose the dataset that contains the data you want to display
3. Select the data variable to be displayed
4. Choose a trace type for the display

To enhance the display you can also add:

• Markers to identify specific data points
• Annotations using text and illustrations
• Legends to help identify specific traces

If you used a template to create the design you have simulated, the initial setup and configuration to create displays for data analysis is done for you automatically.

To create a data display...

1. Click to open a data display
   
   

Viewing Results

To view simulation results from the Main, Schematic, or Layout window choose Window > Open Data Display and use the dialog box to locate and open the results.

To display a list of data display files in the File Browser pane of the Main window you will need to be sure the Show All Files option ( View > Show All Files ) is selected.

To display simulation results...

1. Open Data Display Window
   
2. Select Dataset File
   
3. Display Simulation Results
   
    
   

Display Options

The following plot, trace, and data options can be used to display data for analysis:

Plot Type	Trace Type	Data Source
Rectangular plot Stacked plot Smith chart Polar plot	Auto Bus Linear Scatter Spectral Histogram Digital Sampled	Simulation dataset File Formats - Touchstone - MDIF - Citifile - ICCAP

Using Functions

You can use Measurement Equations to perform operations on data generated during a simulation. These equations are created using functions that are based on AEL, the Application Extension Language.

Note Data from a marker can also be used as part of an equation. To insert a marker, choose Marker > New and click the trace where you want to insert it.

To create and insert a function...

1. Click the Eqn button, and select a spot on the Display window
   
2. The Equation editor will appear, make your changes
