The present invention relates to single-chip microcomputer experiment online simulation platform and provides an online simulation and automatic evaluation method for the experiment hardware of a single-chip microcomputer. The method comprises the steps of connecting a circuit, simulating the process in the on-line manner, and evaluating an experiment result. A user logs in the system through an information management module, and the hardware connection operation of the circuit of a single-chip microcomputer is completed through a circuit connection and on-line simulation module. Meanwhile, the operation result is stored in a circuit connection matrix. The circuit connection matrix is a Boolean array, wherein N represents the number of all pins. If a pin i and a pin j are connected, img file = 'dest _ path _ image 005. TIF 'wi = '72 'he = '37'. Otherwise, img file = 'dest _ path _ image 007. TIF 'wi = '75 'he = '34 '. According to the technical scheme of the invention, firstly, the circuit connection matrix is loaded to a test box through a download and communication module by a user, wherein an FPGA circuit is arranged inside the test box. Through arranging the circuit connection matrix, the configuration of the hardware circuit is completed. Secondly, after the circuit connection of the test box is confirmed, the information is fed back to the user. Thirdly, the configuration confirmation information sent from a lower computer is received by the download and communication module, and the information is verified. In this way, the configuration of the hardware connection is completed. Finally, the user turns on a programming tool for a single-chip microcomputer to compile an experiment program and conduct the experiment operation.
