WRITE DATA CONVERSION METHOD FOR FPGA, OPTICAL TRANSMISSION RECEPTION LEVEL MONITOR METHOD USING THE SAME

PROBLEM TO BE SOLVED: To provide a method for writing write data to an FPGA(field programmable gate array) that can easily realize a setting revision in a logic circuit in a logical circuit design by the FPGA. SOLUTION: In the method of this invention, where data of a logic circuit and its initial setting value are read, write data consisting of binary data are generated on the basis of data of the logic circuit, and its initial setting value and the write data are written in the FPGA, when write data other than desired write data have already been written in the FPGA, binary data for the initial setting value of the write data and the initial setting value of the other write data are revised and written in the FPGA.
