NAME

rfnoc_modtool - RFNoC OOT module management tool

DESCRIPTION

Create and manage RFNoC OOT modules.

SYNOPSIS

rfnoc_modtool [COMMAND] [OPTIONS]

COMMANDS

Run rfnoc_modtool COMMAND --help for more information on a specific command.

create
Create a new RFNoC OOT module.
add
Add a new block to an existing RFNoC OOT module.
add-gr-oot
Add GNU Radio OOT Module.
add-gr-block
Add GNU Radio block to an existing GNU Radio OOT module.
add-grc
Add GNU Radio GRC bindings for an existing block in this RFNoC OOT module.
make-yaml
YAML Creation Wizard -- Generate an RFNoC block YAML descriptor file based on user input.

CREATING NEW MODULES

When running rfnoc_modtool create, a new directory will be created that contains the necessary files for a new RFNoC OOT module. This directory will only contain boilerplate code, and the user will need to add their own blocks to the module.

By calling 'rfnoc_modtool add-gr-oot', the user can add a GNU Radio OOT module inside the RFNoC OOT module.

ADDING BLOCKS

When running rfnoc_modtool add, a new block will be added to an existing RFNoC OOT module. This requires previously having run rfnoc_modtool create to create the module.

Note that in order for 'rfnoc_modtool add' to succeed, the user must provide a block descriptor file in YAML format. This file describes the block and its parameters. The user can create this file manually, or use the YAML Creation Wizard by running rfnoc_modtool make-yaml. The wizard will prompt the user for the necessary information to create a valid YAML file.

Once blocks have been created, the user can add native GNU Radio blocks to enable more precise control over RFNoC blocks from GNU Radio by running 'rfnoc_modtool add-gr-block'.

To add GNU Radio GRC bindings for the blocks, call 'rfnoc_modtool add-grc'.

EXAMPLES

Create a new RFNoC OOT module called filter

rfnoc_modtool create filter
cd rfnoc-filter

Use the YAML Creation Wizard to create a block descriptor file

rfnoc_modtool make-yaml

After editing the fir.yml file to describe the FIR filter block, add a block called fir to the filter module

rfnoc_modtool add fir

Now add a GNU Radio OOT module

rfnoc_modtool add-gr-oot

Add a GNU Radio block to the filter module to control the FIR RFNoC block (e.g., for better integration into the GNU Radio filter design tool)

rfnoc_modtool add-gr-block --gr-blockname rfnoc_fir fir

Expose this new block into GRC

rfnoc_modtool add-grc --binding-type native fir
