The vast majority of them - but perhaps avoid the smaller devices in any family. 

 

There is a project you can download that is targeted at the DE2-115 development board and I've successfully run it on that platform. That dev board is based on a Cyclone IV part. Therefore, almost by definition it could be modified to run on any suitable Stratix or Aria device - that's large enough.

What capacity of this payment (Gh/s) ?

As I understand it the FPGA implementations will generate a hash result per clock so it depends how many cores you 

can fit in, the rate you can feed them data and the max speed you can push your clock. 

 

So several hundred mega hashes per second if it all works out. 

 

I don't think they compete with graphics card solutions.

The sample bitcoin project for the DE2-115 board mentioned before returns an average of 50MH/s, entirely consistent with the 'hash result per clock' identified by Nial. 

 

There is much debate as to the 'power' of FPGA's for mining. The returns they offer simply don't compare (as of today) with those of their processor based cousins.

It isn't enough 50MH/s ((((

Buy a bigger FPGA? Or buy an ASIC?

ASIC. 

ALTERA have ASIC chips?

Hello, what board to choose for mining (Scrypt).  

Anyone have experience? 

What DE5-Net FPGA?

You'll probably be able to find some VHDL code that you could adapt to run on the Cyclone II, but the question is why? Even a software solution using a GPU will be a lot faster.
