Single chip microcomputer hardware simulator and simulation method for same

Abstract

The invention discloses a single chip microcomputer hardware simulator and a simulation method for the same. The simulation method includes the steps: operating a Proteus software on a PC (personal computer) to perform software simulation for a virtual circuit, and selecting a corresponding simulation model during software simulation; utilizing the simulation model to logically process digital level signals of pins of a master controller in the virtual circuit and signals acquired by the single chip microcomputer hardware simulator, and packing the processed signals into a data packet; transmitting the data packet into the single chip microcomputer hardware simulator through a USB (universal serial bus) interface; enabling the single chip microcomputer hardware simulator to receive the data packet from the simulation model and drive an output simulation head to output signals; and enabling a hardware circuit to respond the signals from the simulation head so that hardware simulation is completed. The simulation method realizes interaction and synchronization of the virtual circuit and the practical hardware circuit, so that experimental effect of experimental training equipment is enhanced, and study of students and embedded development and design of developers are facilitated.

Description

technical field [0001] The invention relates to the field of single-chip computer simulation, in particular to a single-chip computer hardware simulator and simulation method based on Proteus software. Background technique [0002] In the design of embedded systems, the scope of simulation applications mainly focuses on the simulation of programs. For example, in the development process of single-chip microcomputer, program design is the most important but also the most difficult. Traditional embedded system simulation software, such as Proteus, has little relationship with embedded hardware systems. Software emulation is pure software emulation and has nothing to do with the hardware system. The disadvantage of software simulation is that it cannot fully simulate the hardware-related parts, so the final design must be completed through hardware simulation. This separation of software and hardware has brought many adverse effects on students and staff learning embedded sy...

The disadvantage of software simulation is that it cannot fully simulate the hardware-related parts, so the final design must be completed through hardware simulation

This kind of separation of software and hardware has brought many adverse effects on students and employees learning embedded system development in schools, training institutions and scientific research enterprises, so that they cannot quickly and accurately master the methods and skills of embedded system development
