Simulink Fixed Point
Design and simulate fixed-point systems
Simulink model demonstrating the effect of limited range and precision on a signal, as shown on the scope (top right). The parameter dialog box (top left) allows full control of block parameters, including all fixed-point attributes.
Simulink Fixed Point™ enables the fixed-point capabilities of the Simulink®product family, letting you use those products to design, simulate, and implement fixed-point control and signal processing algorithms.
With Simulink Fixed Point, you specify fixed-point data attributes, including word length and scaling for signals and parameters, in your model. You can perform bit-true simulations to observe the effects of limited range and precision on designs built with Simulink, Stateflow®, DSP System Toolbox™, and other Simulink products. Automated fixed-point advisors guide you through the steps of converting floating-point models to fixed point. Additional tools analyze your model or use simulation results to recommend data types and scaling.
Simulink Fixed Point supports C, HDL, and PLC code generation with Simulink code-generation products.
