The files thatthe hardware designer provides to the software developers are the MicoSystem Builder project file, the LM32 processor driver files and GNU files, thecomponent driver files, and the FPGA's configuration bitstream.The hardware developer needs to have both Lattice Diamond and LatticeMicoSystem installed in order to generate the files and provide them to thesoftware developer.The following scenario shows the tasks involved:Hardware Developer The hardware developer performs the followingtasks:1. Uses Diamond to create an FPGA development project.NoteWhen doing mixed-language simulation, use the -t 1ps command-line option for the“vsim” command.
