Digilent FPGA board
I had very bad experience with Digilent Spartan2 (Digilab 2) boards in conjunction with their I/O board Digilab DIO2. Due to bad PCB design these boards suffer from noise. Also, DIO2 board had missed connections to VGA port. When I sent letter to them pointing this problem, they released new DIO board with correct connection, but missed output transistors, so VGA port was non-working due to low signal level and noises.
Last time, I had experience with boards from Digilent 2 years ago. Probably, now they are OK, following positive reports in this topic.
