Fixed-Point Designer provides bit-true agreement across a workflow that uses Model-Based Design. The response of a fixed-point algorithm is bit-true for all forms of simulation and code generation, including acceleration and software-in-the-loop. Analysis and verification of a fixed-point algorithm are based on bit-true representations. Bit-true agreement maximizes the benefits of Model-Based Design, such as the ability to discover issues early in the workflow, when they are easier and less costly to fix.
For Simulink models, once a model has been configured with fixed-point data types, you can simulate its performance to explore implementation tradeoffs between limited range and precision for fixed-point embedded systems.
Using the tools in Fixed-Point Designer, you can access these values and change the data types of signals, optimizing precision while ensuring that their range is covered. You can specify data type ranges using design minimums and maximums, simulation results, or derived minimum and maximum results. You can lock output data types to prevent them from being changed.
