I updated the wiki page (http://gnuradio.org/trac/wiki/UsrpTxModifications) again, added the command block FSM and renamed the fifos as Eric proposed. If nobody see any major problem, I can start to implement these modifications by working on the tx_usb_block.

Here is what I think that could become an issue:

- The data_bus (used to transfer data between blocks) is 32 bits wide which might be an overfill.

- I don't do know how hard it is to add the "skip" functionality to the Altera Fifo.

Is Quartus Web Edition able to run simulation like ModelSim? It looks like it can but it wants the inputs to be defined in Vector Wave File whereas I would rather generate them using my own testing blocks. I would like to start by writing some testing blocks for the tx_usb_block.
