USB Simulator Design And Implementation

USB simulator is an important component of our full system simulator. System simulator simulates embedded systems by software. System simulator is used for mobile telephone and digital product's software development. System simulator consists of CPU simulator and device simulators. USB simulator belongs to device simulator.USB simulator simulates the function of embedded hardware board's USB subsystem. USB simulator references Intel PXA270 processor's USB host/client controller. USB simulator is designed by using Object Oriented method and implemented to simulate USB host/client controller's logic and register interface. USB driver program can interact with the USB simulator, just like operating on a hardware USB controller. In embedded product design, using USB simulator can speed up and simplify target USB software design and test work.
