Abstract

The invention discloses a hardware simulation device. The device comprises a power supply module, a communication module and a plug-in module. The power supply module is used for supplying power to a simulated chip and a peripheral device, the communication module is used for being connected and communicated with a computer, and the plug-in module is used for being connected with the power supply module and the communication module and is further connected with externally-arranged hardware. The hardware simulation equipment for conducting general, immediate and low-speed simulation on embedded type processing cores, such as a microcontroller, a microprocessor and a DSP is designed, and the device is applied to the embedded type system teaching and research and development field. A complete program file does not need to be modified and compiled, time is saved, errors can be rapidly found, the system problem is solved, the correctness of the working process and the hardware design is determined, the cost of hardware in loop simulation equipment is reduced, and varieties of supported chips are more.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a hardware simulation device and system. Background technique [0002] With the development of current technology, there are three main technologies for microprocessor simulation: software simulation, hardware simulation, and hardware-in-the-loop. The software simulation technology simulates the work of the microcontroller through the software simulation kernel. When using it, write the program code first and compile it. The emulator executes the compiled program instructions according to a certain plan, and displays some collected results. screen output to the user. Hardware emulation technology uses the combination of emulator and simulated microcontroller, and uses JTAG and other technologies to track system status and control system operation in real time. The simulation process requires complete program code support. Hardware-in-the-loop simulation technology uses ...
