Arcade Machine is a hardware architecture designed to implement the well know game - Pong - in verilog, which will be developed to be deployed in the Digilent Basys2 board. The players make use of four buttons in a PS/2 Keyboard in order to control the position of the rackets. The game is displayed in a monitor using VGA output. Also, the score of the game is displayed in a seven segment display. Additionaly, two buttons are used to start the game and reset it.
For this project, the picoVersat - minimal hardware controller - will be used as a state machine. Specialized hardware will be created to handle the PS/2, the VGA and the seven segment display interfaces.

All the peripheral hardware interface modules were developed in rtl directory, these were used in the PicoVersat top model, which corresponds to the top model of the project itself. The top model is located in picoversat/rtl/src directory in a file called xtop.v.
To simulate peripheral hardware interface modules, go to the peripheral directory given by rtl/<name_of_peripheral> and execute the Makefile, the simulation output file has .vcd extension and will be located in the same directory of the makefile.
To simulate the top model, this is the Arcade Machine as a whole just go to picoversat directory and do:
make icarus test=test_am3
The simulation output file will be located in picoversat/simulation/icarus directory.
It is required to have Xilinx ISE 14.7 installed. Just open the picoversat.xise located in picoversat/fpga/xilinx/14.7/picoversat and generate programming file.
