Design Software Architectures

Author, simulate, and deploy software architectures and generate code

System Composer™ software architectures provide capabilities to author software architectures composed of software components, ports, and interfaces. Use System Composer to design your software architecture model, define the execution order of your functions from your components, simulate your design in the architecture level, and generate code.
