DSP Builder technology allows you to go from system definition/simulation
using the industry-standard The MathWorks/Simulink tools to system
implementation in a matter of minutes.

The DSP Builder Signal Compiler block reads Simulink Model Files (.mdl) that
are built using DSP Builder and MegaCore« blocks and generates VHDL files
and tool command language (Tcl) scripts for synthesis, hardware
implementation, and simulation.
