Data Visualization
While the tasks involved in model-based systems development (MBSD) cover an enormous range of activities, they share a common need for data visualization. In some cases, the engineer wishes to visualize the results of a simulation, or compare multiple simulation runs. In other cases, they wish to view a variety of data that was sampled from hardware testing. Emmeskay understands these needs and has built several tools to facilitate the MBSD process.
MVD Player
Map-Video-Data or MVD Player is a tool created to facilitate the work done for vehicle road tests. MVD Player allows the engineer to synchronize a set of time-dependent data streams and control how they view that data. While the original purpose of the tool was to synchronize GPS, video and sensor data, MVD Player is capable of much more. See the MVD Player page for more information.
mTm
Model Test Manager or mTm is a software tool designed to facilitate
Simulink model inspection. By using mTm, the engineer can simply pick
from a list of existing signals to automatically insert "sensors" in
their model. Likewise, they can instrument their model with
"actuators" to determine which signals they wish to use as inputs for
automated model testing. This instrumentation is stored separately
from the model, allowing them to keep their original model as it
existed, while storing the set of signal they wish to sense or actuate
in a separate file. All these capabilities allow engineers to
visualize their model behavior in a simple way, thereby facilitating
their model-based systems development. See the mTm page for more information.
SBPlot
SBPlot is another MATLAB-based utility developed by Emmeskay to facilitate model development and analysis. SBPlot allows the engineer to load several signals into a single figure window. The utility can be used to select various values of the independent variable (e.g., time) in order to determine the values of the selected dependent variables. The dependent variable values are displayed as the user manipulates the slider bar or x-value edit box, making it very simple to evaluate the model behavior or to compare two signals on the same axis.
