The FPGA is the hub of the digital control board and all other chips are connected to and controlled by it.  This article discusses the programming of the FPGA.  All code is written in [http://en.wikipedia.org/wiki/VHDL VHDL].  For the purposes of testing, each chip has not only a controller written for it, but an emulator as well.

''Open question:'' What is the clock speed of the FPGA?  Timing constraints must be taken into account to link the multiple blocks.
