Re: [Discuss-gnuradio] packets to the usrp and loopback

[Thibaud Hottelier]

Hi,

I moved all my small testing blocks from ModelSim to the Quartus source 
tree. I am writing the glue code between the modules so we should have 
the basic Tx functionality working relatively soon. But before that, I 
would like to simulate to whole Tx block in ModelSim, so I need some 
information about how the tx_chains work.

A what rate should I send the samples to the tx_chains? Every 4 clock 
cycles? They seems to be controlled by tx_strobe, but I failed to 
understand what this signal actually mean.

What is the point of the bus_reset and the clear_status signal? They are 
both input to current tx_buffer.

As we report overrun/underrun in packet header, are we gonna get rid of 
the tx_empty, have_space and tx_underrun signal ?

Comments on the code I checked in are welcome...
