FPGA Cyclone III Dev Board

This board serves as the main computing board for several FPGA-related projects.
It is the first revision in an attempt to creatign a design that can read analog samples, store then in DRAM, and read them out for display over HDMI.
The Rev. A needs an external ADC module that has no analog front end.

Known issues:

• All green LEDs are too bright. Select higher dropper resistors for LED2, LED3, LED4, LED5, LED6, LED7.
• C101 and C105 need to be removed or not mounted! They cause  high rippel in the 1V8 and 3V3_LDO rails, leading to destruction of the ADV7513 (HDMI IC).
