2.6. DSP Builder for Intel® FPGAs Design Flow

DSP Builder for Intel® FPGAs shortens digital signal processing (DSP) design cycles by helping you create the hardware representation of a DSP design in an algorithm-friendly development environment.

This IP core supports DSP Builder for Intel® FPGAs. Use the DSP Builder for Intel® FPGAs flow if you want to create a DSP Builder for Intel® FPGAs model that includes an IP core variation; use IP Catalog if you want to create an IP core variation that you can instantiate manually in your design.
