NOTE: After some time the compilation of the simulator gets sluggisly slow.
I noticed that deleting the Libraries and re-creating them re-vitalizes the speed
In order to do so start a simulation (so that the Library is loaded), make sure that you end the current simulation, and type 'RemoveAllLibraries'. After a vsim re-start everything shoudl run faster

RUN ON BOARD
============
COMMUNICATE WITH BOARD
----------------------
UART: BAUDRATE 115200, 8N1
Login: USER=root, PASS=root
MAC: A2:F9:79:A9:F8:10
$picocom -b 115200 -d 8 -y n -p 1 /dev/ttyUSB0
NOTE: Before unplugging the board, execute the 'halt' command to shutdown the board and prevent data corruption.
The '~/test/udp_forwarder' is used to forward UDP packets ariving at the Linux side running on the ARM processor over to the FPGA, and back out.
USAGE: ~/test/udp_forwarder ADDRESS DOMAIN_ID
ADDRESS The SRC IPv4 Address of the FPGA implementation (In x.x.x.x format)
NOTE: The system has to have a interface with the same address
DOMAIN_ID The Domain ID of the FPGA implementation
RBF FILE
--------
The board automatically flashes the 'soc_system.rbf' file in the root of the SD card to the FPGA.
In order to create a *.rbf file from a *.sof file, you have to follow following instructions:
* In Quartus go to "File"->"Convert Programming Files"
* Select "Programming file type" = "Raw Binary File (.rbf)"
* Select "Mode" = "Passive Parallel x16"
* Select output file name/location
* Select the respective *.sof file in "Input files to convert"
* Click "Generate"
NOTE: Don't forget to rename the file to "soc_system.rbf" when inserting it to the SD Card
(All other *.rbf files are ignored. You could thus keep multiple backup files around)
