5 Simulation Results

The user interface displays the results after simulating a particular setup. This page has several points for the user to interact with (Figure 5-1).

GUID-20231114-SS0I-VSST-JLQG-SC1J1SGHQVNG-low.svg Figure 5-1 Simulation Outputs
  1. Edit Design: Click the Edit Design tab to return to the simulation input panel.
  2. Simulation Environment: Navigate this feature as described in Section 3.
  3. Play: Select this button to play an animation of the magnet motion. The progress slider can be clicked and dragged to set the animation to a specific frame. Watching the full animation is helpful to verify the input parameters related to magnet motion are correct and match expectations. This is particularly useful in cases where the magnet is rotated.
  4. Sensor Select: Select this option for simulations with more than one sensor to switch the field and output results to display the simulation results for the selected sensor.
  5. Die Select: Select this feature to display the results for the selected die in devices with more than one die.
  6. Magnet Field Density Versus Distance: This plot displays Magnetic Flux Density in millitesla versus the travel of the magnet. This plot demonstrates the sensor orientation and not the global coordinate space. The field is calculated based on the alignment shown in Appendix A if the sensor is rotated.
    1. Single click the trace in the legend to remove individual results in the plot from view.
    2. Double click the trace in the legend to keep all results from view in the plot except selected results.
    3. Hovering over any trace with the selection tool shows the value of the field at that point.
    4. Use the selection tool scroll wheel to zoom in on the plot.
    5. Select the home icon to return to the full view of the plot.

    6. Click the double arrow icon in the top right of the panel to create an enlarged pop-out of the graph.

  7. Device Output - Emulated device outputs are overlaid in the device output plots. Outputs of the same type are overlaid on a single graph. This plot can be manipulated using the same controls as the input magnetic field plot.
  8. Scroll Bar - Using the mouse scroll wheel over the plot zooms the plot instead of advancing to the next plot. Some devices have more than one output mode. When this scroll bar is present there is another plot available by scrolling down.
  9. Input Parameters - This tab expands and collapses to show the parameters used for the simulation. This is helpful for allowing the user to remain on the simulation outputs page without needing to navigate to Edit Design, which removes the output results from view.
