DSP Builder for Intel® FPGAs

DSP Builder for Intel® FPGAs is a digital signal processing (DSP) design tool that allows push-button HDL generation of DSP algorithms directly from the MathWorks* Simulink* environment on Intel FPGAs. The tool generates high quality, synthesizable VHDL/Verilog code from MATLAB functions and Simulink models. The generated RTL code can be used for Intel FPGA programming. DSP Builder for Intel FPGAs is widely used in radar designs, wireless and wireline communication designs, medical imaging, and motor control applications.

DSP Builder for Intel FPGAs adds additional library blocks alongside existing Simulink libraries with DSP Builder for Intel FPGAs (Advanced Blockset) and DSP Builder for Intel FPGAs (Standard Blockset). Our recommendation is to use DSP Builder for Intel FPGAs (Advanced Blockset) for new designs. 

To evaluate Intel FPGAs for a model-based design flow, you will need a license for DSP Builder for Intel FPGAs, the Intel Quartus® Prime design software, MathWorks MATLAB/Simulink, and MathWorks Fixed-Point Designer (sold separately). Request for a 30-day trial of MATLAB and Simulink products for use with DSP Builder for Intel FPGAs.

What's New


DSP Builder for Intel FPGAs enables the implementation of DSP designs with high performance and productivity benefits. Here are some highlighted features:

  • Go from high-level schematic to low-level optimized VHDL targeted for Intel FPGAs
  • Perform high-performance fixed- and floating-point digital signal processing (DSP) with vector processing, such as complex IEEE 754 single-precision floating point
  • Perform push-button design migration to Intel's hard floating-point DSP block in Intel Arria® 10 and Intel Stratix® 10 devices
  • Build custom arithmetic logic unit (ALU) processor architectures from a flat data-rate design with ALU folding
  • Perform high-level synthesis optimizations, auto-pipeline insertion and balancing, and targeted hardware mapping
  • Build custom fast Fourier transform (FFT) algorithms using a flexible ‘white-box’ fast Fourier transform (FFT) toolkit with an open hierarchy of libraries and blocks
  • Use a designer-specified system clock constraint to automatically pipeline, time-division multiplex/fold, and close timing
  • Access advanced math.h functions and multichannel data
  • Generate resource utilization tables for all designs without a Intel Quartus Prime software compile
  • Automatically generate projects or scripts for the Intel Quartus Prime software, Timing Analyzer, Platform Designer (formerly Qsys), and ModelSim*-Intel FPGA Edition
