In order to practice myself in Verilog and VHDL, I used this
little circuitry and modified it into this
Its just for fun and I really like the result of such a small source code with fading in/out feature of led!

The circuitry is clocked at 28MHz and the original Clock.v module was used.
JOY1 port is assigned as output. There just is 6 wire available, therefor only a "0" can be displayed. To make all 8 segment glow, another 2 wire of some other fpga pin is required.
I know this is nothing spectacular, its just fun and I would like to see some more
