Portable comprehensive electronic experimental platform on basis of field programmable gate arrays

Abstract

The invention relates to a portable comprehensive electronic experimental platform on the basis of field programmable gate arrays, and belongs to the technical field of electronic technology teaching equipment and virtual instruments. The portable comprehensive electronic experimental platform comprises an FPGA (field programmable gate array) hardware circuit board, and is characterized by further comprising a PC (personal computer), a LabVIEW-based virtual instrument application program and system configuration data; the LabVIEW-based virtual instrument application program is stored in the PC, and the system configuration data are stored in a configuration chip of the FPGA hardware circuit board; the FPGA hardware circuit board comprises an FPGA chip, a control circuit of the FPGA chip, the FPGA configuration chip, a USB (universal serial bus) communication module, a signal conversion module, a power management module and an external module. The portable comprehensive electronic experimental platform has the advantages that the platform has functions of oscilloscopes, signal generators, direct-current power sources and FPGA development boards; a student only needs to carry the experimental platform and the laptop computer, so that digital circuit, analog circuit and FPGA experiments can be carried out at any time in any places, and basic requirements of the student on carrying out the electronic technology experiments can be met in the aspects of portability, functionality and performance.

Description

technical field

[0001] The invention belongs to the technical field of electronic technology teaching equipment and virtual instruments, in particular to a teaching experiment device for digital circuits and analog circuits. Background technique

[0002] Digital Integrated Circuit (Digital Integrated Circuit, referred to as digital IC) is divided into two categories: general-purpose and special-purpose.

[0003] After the general-purpose digital IC leaves the factory, designers can implement various specific applications based on it. For example, a piece of NAND logic operation IC can be used to realize addition operation circuit and multi-person voter circuit. However, this IC always implements AND and non-logic operations, and cannot be programmed to implement other logic operations.

[0004] Special-purpose digital ICs are designed for specific applications. For example, ICs specially designed for digital weighing scales can only be used to develop applications related...
