The Fixed-Point Tool is a user interface that automates specifying fixed-point data types in a model. The tool collects range data for model objects. The range data comes from either design minimum and maximum values that objects specify explicitly, from logged minimum and maximum values that occur during simulation, or from minimum and maximum values derived using range analysis. Based on these values, the tool proposes fixed-point data types that maximize precision and cover the range. You can then review the data type proposals and apply them selectively to objects in your model.
