Working mode switching control method of electronic product circuit containing FPGA

Abstract

The invention discloses a working mode switching control method of an electronic product circuit containing an FPGA, and the method comprises the steps of: performing switching to a second working mode after the FPGA is powered on under the condition that an operation parameter of the electronic product circuit is smaller than a first preset value needed by the operation of a first working mode, wherein the second working mode is used for correcting the operation parameter value based on an FPGA configuration circuit; performing switching to the first working mode when the operation parameteris corrected to the first preset value; and in the second working mode, enabling the FPGA configuration circuit to execute the working method. On the basis of judgment of the operating parameter, whenthe condition of entering the first working mode is not met, the operating parameter is corrected by switching to the second working mode until the condition of entering the first working mode can bemet, and then working is performed in the first working mode, so that the auxiliary effect of starting the first working mode is achieved, and the influence of the operation parameter on the first working mode is avoided.

Description

technical field [0001] The invention relates to the field of FPGA technology, in particular to a working mode switching control method of an electronic product circuit containing FPGA. Background technique [0002] The complexity and diversity of the external environment will have varying degrees of impact on electronic products. There are basically three types of external environmental impacts: climate factors, mechanical factors and electromagnetic interference (noise interference). Climatic factors include temperature, humidity, air pressure and other main factors, as well as salt spray, dust, mold, sunlight, etc. The impact of low air pressure on electronic products is as follows: easy breakdown; increased arcing and corona phenomena. Electromagnetic interference There are electromagnetic waves generated by various reasons inside and outside electronic products. Except for the signal that the equipment wants to receive, the rest of the electromagnetic waves are interfere...

Problems solved by technology

Electromagnetic interference can be divided into external interference and internal interference. Its existence will change the performance parameters of the machine, such as unstable work and increased noise. In severe cases, the machine will not work normally.

[0003] Therefore, in order to improve the reliability and robustness of electronic product circuits, some protective measures need to be a
