This is an area where Proteus VSM excels. Typically, engineers spend as much time finding and fixing problems and testing projects as they do in creating them in the first place. In the world were time to market is becoming more and more important, this is a real advantage. With Proteus VSM it is possible to simulate complete microcontroller systems and thus to develop the software without access to the physical prototype. PROTEUS VSM is a simulation software that allows professional engineers to run interactive simulations of real designs.
