Model Composer allows device-specific hardware designs to be constructed directly in a flexible high-level system modeling environment. In a Model Composer design, signals are not just bits. They can be signed and unsigned fixed-point numbers, and changes to the design automatically translate into appropriate changes in signal types. Blocks are not just stand-ins for hardware. They respond to their surroundings, automatically adjusting the results they produce and the hardware they become.
Model Composer allows designs to be composed from a variety of ingredients. Data flow models, traditional hardware description languages (VHDL and Verilog), and functions derived from the MATLAB programming language, can be used side-by-side, simulated together, and synthesized into working hardware. Model Composer HDL block simulation results are bit and cycle-accurate. This means results seen in simulation exactly match the results that are seen in hardware. Model Composer simulations are considerably faster than those from traditional HDL simulators, and results are easier to analyze.
