Model Composer provides a system integration platform for the design of DSP FPGAs that allows the RTL, Simulink® , MATLAB® and C/C++ components of a DSP system to come together in a single simulation and implementation environment. Model Composer supports a black box block that allows RTL to be imported into Simulink and co-simulated with either Questa or AMD Vivado™ simulator, and provides an AMD Vitis™ HLS block that allows integration and simulation of C/C++ sources.
