Logging Function
The logging part of the FPGA acquires the external input/output from the user circuit, count values, and other sources at the
timing of when the sampling pulse is input, and writes them to DDR3L SDRAM. Since data before and after the occurrence of
a problem can be stored, it can be used for phenomenon analysis. The logged data can be transferred to an FTP server using
the FTP client function.
