精选示例
Working with Fixed-Point Code
HDL code generation from a fixed-point MATLAB® design that is ready for code generation.
Floating-Point to Fixed-Point Conversion
Start with a floating-point design in MATLAB®, iteratively converge on an efficient fixed-point design in MATLAB, and verify the numerical accuracy of the generated fixed-point design.
Fixed-Point Type Conversion and Refinement
Achieve your desired numerical accuracy when converting floating-point MATLAB® code to fixed-point code using the HDL Workflow Advisor.
Working with Generated Fixed-Point Files
Work with the files generated during floating-point to fixed-point conversion.
Fixed-Point Type Conversion and Derived Ranges
Achieve your desired numerical accuracy when converting fixed-point MATLAB® code to floating-point code using static range analysis which helps to compute derived ranges of the variables from design ranges.
