Description

technical field [0001] The invention relates to the field of circuits and systems, in particular to an FPGA reconfiguration device and method. Background technique [0002] FPGA (Field-Programmable Gate Array, Field Programmable Gate Array), which emerged as a semi-custom circuit in the field of application-specific integrated circuits, not only solves the shortcomings of custom circuits, but also overcomes the shortcomings of the original programmable device gate. The disadvantage of limited number of circuits. Due to its high integration, rich internal logic resources, small size, low power consumption, and high cost performance, FPGA devices are widely used in the design of various electronic products, and mostly undertake the tasks of the main controller of various electronic systems and modules. [0003] At present, in order to achieve the coverage rate of FPGA functional performance test, FPGA devices are usually tested by "divide and conquer", that is, test programs ...
