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.
Looks cool to me.
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.
32-bits should be OK. What problems do you think you may have an issue with?
- I don't do know how hard it is to add the "skip" functionality to the Altera Fifo.
You will probably have to create your own FIFO from the lopsided RAM. I don't think there is a way to infer a RAM where side A is a different size than B. The skip functionality is pretty straight forward, and you probably just need empty and full flags. That shouldn't be difficult.
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.
They have a version of ModelSim you can download and use the Altera blocks all for free. I'd recommend just using that and not going through the Altera tool. Write a normal testbench and test out that FIFO.

If you need me to verify any results or help with any of your coding, just ask. I have ModelSim along with the Altera tools available to me.
