Note: Post-fit timing simulation is supported only for Stratix IV and Cyclone IV devices in the current
version of the Quartus II software. Altera IP supports a variety of simulation models, including
simulation-specific IP functional simulation models and encrypted RTL models, and plain text
RTL models. These are all cycle-accurate models. The models support fast functional simulation of
your IP core instance using industry-standard VHDL or Verilog HDL simulators. For some cores,
only the plain text RTL model is generated, and you can simulate that model. Use the simulation
models only for simulation and not for synthesis or any other purposes. Using these models for
synthesis creates a nonfunctional design.

DSP Builder Design Flow
DSP Builder 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. Use the DSP Builder flow if you want to create a DSP Builder 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. For more information about the DSP Builder flow, refer to the
