Once a design has been created or imported, the user can now simulate the design by selecting the red “Simulate” button at the bottom of the 2D slice window, as shown in Figure 5-1.
Figure 5-1 Simulation ButtonOnce the user initiates the simulation, the 2D slice window displays an animation of the light source moving in an arc above the sensor. The light source sweeps from -90 degrees to +90 degrees, and the amount of light illuminating the sensor area for each angle of incidence is logged in the background. Once the simulation is complete, the angular response graph is displayed to the right side of the simulation window, as shown in Figure 5-2.
Figure 5-2 Angular Response PlotOn the top right of the plot window, the user can expand the plot as shown in Figure 5-3 and Figure 5-4.

GraphThe generated plot is interactive, meaning you can hover over the different angles and view the sensor response, as shown in Figure 5-5.
Figure 5-5 Plot Hover FeatureFor multi-channel sensors like the OPT4048 (XYZ sensor) and the OPT4003 (ALS + IR sensor), the plot contains the angular response for all channels. Figure 5-6 and Figure 5-7 depicts the angular response of a 4-channel and 2-channel sensor, respectively.
