rtio-nmigen

Formally verified implementation of the ARTIQ RTIO core in nMigen

File Synopsis

LICENSE: License terms (LGPLv3+) for this project
README.md: this document
shell.nix: Nix file for setting up the environment for this project
rtio: RTIO core in nMigen

Running the verification tasks

Currently, only the sorting network contains assertions to be verified. To run the verification tasks for the sorting network, change directory to the root of this project, set up the Nix environment by running nix-shell and do

$ python -m rtio.test.sed.output_network

Progress

Devise a suitable migration strategy for artiq.gateware.rtio from Migen to nMigen
Implement the core in nMigen
- rtio.cri (Interface and CRIDecoder only)
- rtio.rtlink
- rtio.sed.layouts
- rtio.sed.output_network
- rtio.sed.output_driver
Add suitable assertions for verification (BMC / unbounded proof?)
- rtio.cri (Interface and CRIDecoder only)
- rtio.rtlink
- rtio.sed.layouts
- rtio.sed.output_network - Sorting network (high priority)
- rtio.sed.output_driver
Restructure to code to follow nMigen convention and re-validate existing assertions
- rtio.cri (Interface and CRIDecoder only)
- rtio.rtlink
- rtio.sed.layouts
- rtio.sed.output_network
- rtio.sed.output_driver
