Research of Space Electronic Circuit Optimization Design

Abstract

During the space electronic system in carries out the exploratory mission in the deep space, it maybe faced with kinds of violent natural environment, to electric circuit's performance, the volume, the weight and the stability proposed a higher request, the traditional circuit design method already more and more with difficulty satisfied this kind of request. The traditional circuit design method already more and more with difficulty satisfied this kind of request. But unifies the programmable component and the evolutionary algorithms hardware may the dynamic change hardware's structure adapt the adverse circumstance, resume the damage of the function, the adaptation for the duty change. In view of the Xilinx Company's FPGA unique feature, proposed one kind of evolutionary algorithms which uses in the space electronic system circuit optimization design and through the experiment proved, the algorithm obtains the circuit structure to surpass the tradition circuit design method.

“…A schematic description was used to design the electronic circuit. [5] In order to generate the program file, it is necessary to create a file in which each input and output terminal is associated with a corresponding pin of the FPGA circuit used. This is achieved by the existence of a User Constraints File that contains an association between the input/output ports and the FPGA circuit pins.…”
