Re: [Discuss-gnuradio] Add RFNoC FIFO

[Vishwesh Rege]

Hi,

What are the list of blocks that I can add?

For example,

Looking at the list of blocks in usrp3_rfnoc/lib/rfnoc/Makefile.srcs

>From these I could add noc_block_digital_gain (built successfully)

but couldn't add chdr_fifo_large (running make X310_RFNOC_HLS_HG gave an error)

How do I know which blocks will work?

For the error I'm getting in GRC "FIFO_0 block missing" I think noc_block_axi_fifo_loopback is probably the right one

But what functionality do the other FIFOs provide (when am I supposed to use them)?

chdr_fifo_large
noc_block_axi_dma_fifo
split_stream_fifo
ram_to_fifo ... etc.

Thanks,

Vishwesh

To change the blocks, you need to edit rfnoc_ce_auto_inst_x310.v twice:
You need to change NUM_CE (at the top), and then the actual block list.

For FIFOs, you can go to the bottom and use the generate for loop to add
more FIFOs.

You can use make.py to autogenerate this file (in
usrp3/tools/scripts/make.py).

Cheers,
Martin
