Embodiment 1

[0023] see figure 1 , on-line simulation and automatic evaluation method of single-chip experimental hardware of the present invention, including circuit connection and on-line simulation process and automatic evaluation process of experimental results:

[0024] In the experimental operation stage, the user logs into the system / platform through the information management module, completes the hardware connection operation of the single-chip circuit through the circuit connection and online simulation window, and stores the operation results in the connection matrix;

[0025] The connection matrix is ​​L N×N is a Boolean square matrix, where N represents the number of all pins; if there is a connection between two pins i and pin j, then l i×j = 1; otherwise l i×j =0; connection matrix L N×N It is a symmetrical matrix, and only the content in the upper triangle can be stored in the database, so there is a matrix transformation operation between the connection matrix and the d...

Embodiment 2

[0031] see figure 1 The difference between the on-line simulation and automatic evaluation method of the single-chip experimental hardware of this embodiment and the first embodiment is that the user writes the experimental program through the single-chip programming tool, and at the same time, includes the implanted program of the system in the source file. The bit computer (user computer) simulation software feeds back the register status of the single-chip microcomputer; after the single-chip program is successfully compiled to generate a *.hex file, use the program download tool to download the program to the single-chip microcomputer;

[0032]Next, the user opens the online simulation function in the simulation software to monitor the experiment process in real time; finally, the simulation software gives evaluation results to the user's experiment process according to the user's hardware connection and software monitoring situation.

Embodiment 3

[0034] see figure 1 , the single-chip experimental hardware online simulation and automatic evaluation method of the present embodiment, the difference from embodiment 1 or embodiment 2 is: the automatic evaluation process of the experiment, adopts the automatic evaluation module of the experiment to learn the experimental circuit according to the setting of the connection matrix hardware connection, and give a judgment on whether the hardware connection is correct or not; at the same time, the automatic evaluation module of the experiment judges whether the software is working correctly according to the status of the MCU registers downloaded and uploaded by the communication module; Students are given a comprehensive assessment of this experiment.

[0035] In the experimental operation stage, the download and communication module receives the register status of the single-chip microcomputer uploaded by the test box in real time, and dynamically simulates the running status of...

Abstract

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.

Description

technical field [0001] The invention relates to an online simulation platform for a single-chip experiment, in particular to an online simulation and automatic evaluation method for a single-chip experiment. Background technique [0002] As a highly practical course, the application of single-chip microcomputer technology must be equipped with corresponding experimental equipment to achieve satisfactory teaching results. Having a fully functional experimental platform is an important prerequisite for the smooth development of experimental teaching. The traditional single-chip microcomputer experiment is completed through an experimental device with fixed hardware, single function and expensive price. These experimental devices are not only easily damaged during the experiment, but also because the experimental method is limited by the fixed hardware connection, the experiment appears monotonous and old-fashioned. Therefore, such experiments can easily limit students' think...
