• Modeling Fixed-Point Designs
• Simulating Fixed-Point Designs
• Generating and Deploying Production Code

Introduction

Simulink Fixed Point™ enables the intrinsic fixed-point capabilities of the Simulink® product family, letting you use those products to design control and signal processing systems that will be implemented with fixed-point arithmetic.

You can perform bit-true simulations to observe the effects of limited range and precision on designs built with Simulink, Stateflow®, Signal Processing Blockset™, and other blocksets. Automated fixed-point advisors guide you through the steps to convert floating-point models to fixed-point representations. Fixed-point scaling tools assess and optimize fixed-point behavior based on design ranges and model simulation results.

When used with MathWorks code generation products, Simulink Fixed Point lets you generate C and HDL code that will implement your design.

Key Features

• Fixed-point modeling and simulation in Simulink, Stateflow, Embedded MATLAB™ Function block, Signal Processing Blockset, and other blocksets
• Bit-true, fixed-point arithmetic for code generated by MathWorks C and HDL code generation products
• Control of fixed-point data type and of scaling from 1 to 128 bit word sizes
• Automated advisors for converting models from floating- to fixed-point data types
• Tools for identifying overflow and saturation errors
• Automatic scaling tools for trading off range and precision
• Customizable operators and math functions, to replace native operators and math functions in code generated by Real-Time Workshop Embedded Coder™
