FPGA (field programmable gate array) development board based detection method for optical interconnection network topology structural performance among boards

The invention discloses a FPGA (field programmable gate array) development board based detection method for optical interconnection network topology structural performance among boards. On the basis of optical interconnection performance among the FPGA detection boards and the interconnection structure on FPGA structural pieces, each FPGA structural piece is provided with receiving and sending ports performing information exchange with the other boards and comprises a data package module, a data sending module, a data receiving module, a data detecting module and a control module, and the above modules are connectively structured through one top module and can be simulated in different platforms. Data sending time delay, data sending error rate and data throughout of the entire network topology structure can be detected. The detection method is good in adaptability and is applicable to interconnection ends with different numbers, the network topology structures different in form and optical devices different in specifications.
