flxlibs - FELIX card software and utilities

Appfwk DAQModules, utilities, and scripts for the FELIX readout card.

Building and setting up the workarea

How to clone and build DUNE DAQ packages, including flxlibs, is covered in the daq-buildtools instructions. You should follow these steps to set up your workarea that you can then use to run the following examples. You also need the felix external package that ships a build of a partial set of the ATLAS FELIX Software suite. This external is set up, if you followed the instructions correctly.

Disclaimer

The Initial setup of FELIX page doesn't mean to be a replacement for the official FELIX User Manual. For a much more detailed documentation, always refer to that appropriate RegisterMap version and device's user manual, that are found under the official FELIX Project Webpage.

FELIX setup

Please ensure the following:

  1. For the physical setup, please refer to the Initial setup of FELIX.

  2. For the card configuration, one needs compatible firmware and FELIX configuration sets. The list is under FELIX Assets.

  3. Use the Local driver from the appropriate dunedaq release.

  4. Configure the FELIX card, as explained in the Enabling links and setting up the FELIX card manual.

  5. Load data into the emulator of the FELIX card based on the Configuring the EMU manual.

  6. Run basic tests explained in the Basic tests manual to ensure that the card is properly set up.

Examples

After successfully following the configuration instructions, you can try to run a test app that uses the FELIX. First, create a configuration file if real front-end is connected to the card (enable all ADC links):

python -m flxlibs.app_confgen -n 10 -m "0-4:0-4" felix-app.json

If the FELIX is on the emulator fanout and the internal emulator is loaded, apply also frame specific emulation for the DatalinkHanders to overwrite frame signatures (e.g.: timestamp, sequence number, etc.):

python -m flxlibs.app_confgen -n 10 -m "0-4:0-4" -e felix-app.json

Then run it with:

daq_application -c stdin://felix-app.json -n felix_10_links

You can now issue commands by typing their name and pressing enter. Use init, conf and then start. You should see periodic operational info as json printed out every 10 seconds. Verify that rate_payloads_consumed is around 166 for the links.
