## 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](https://nixos.org) environment by running `nix-shell` and do
To run the verification tasks for the sorting network (unbounded proofs with variable numbers of lanes), change directory to the root of this project, set up the [Nix](https://nixos.org) environment by running `nix-shell` and do
```bash
$ python -m rtio.test.sed.output_network
```
## Progress
- Devise a suitable migration strategy for `artiq.gateware.rtio` from Migen to nMigen
- [x] Implement the core in nMigen
- - [x] `rtio.cri` (`Interface` and `CRIDecoder` only)
- - [x] `rtio.rtlink`
- - [x] `rtio.sed.layouts`
- - [x] `rtio.sed.output_network`
- - [x] `rtio.sed.output_driver`
- [ ] Add suitable assertions for verification
- - [ ] `rtio.cri` (`Interface` and `CRIDecoder` only)
- - [x] `rtio.sed.output_network` - Sorting network (high priority)
- - [ ] `rtio.sed.output_driver`
- [x] Restructure to code to follow nMigen convention and re-validate existing assertions (if any)
- - [x] `rtio.cri` (`Interface` and `CRIDecoder` only)
- - [x] `rtio.sed.output_network`
- - [x] `rtio.sed.output_driver`
- [ ] Simulate RTIO command for switching TTL
This should complete in under an hour. The time to complete each verification task (2 lanes, 4 lanes, 8 lanes) is printed to standard output.
