Here is an example subsystem for using cocoTB to interface with an AXI system.
The subsystem comprises of:
- NIC400 bus interconnect
- DMA350 direct memory access controller
- 2x BP140 internal AXI memories with behavioural SRAMs
The subsytem is supplied as configuration files which have to be compiled using ARM Socrates, or configuration scripts from ARM.
## Getting started
The NIC400 is configure with 2 Master/Initiator ports, and 3 Slave/Subordinate ports. The 2 masters are connected to the 2 SRAMs (SRAM0 and SRAM1). The 3 slave ports are for the debug port, DMA M0, and DMA M1.
To make it easy for you to get started with GitLab, here's a list of recommended next steps.

Seperate IP you will need is NIC400, DMA350, and BP140. You will also need a license for the socrates interconnect assistant for NIC400. This is all available under Arm Academic Access.
You will also need to associate these IPs with socrates.

# Editing this README
When you're ready to make this README your own, just edit this file and use the handy template below (or feel free to structure it however you want - this is just a starting point!). Thank you to [makeareadme.com](https://www.makeareadme.com/) for this template.
## Suggestions for a good README
Every project is different, so consider which of these sections apply to yours. The sections used in the template are suggestions for most open source projects. Also keep in mind that while a README can be too long and detailed, too long is better than too short. If you think your README is too long, consider utilizing another form of documentation rather than cutting out information.
## Name
Choose a self-explaining name for your project.
## Description
Let people know what your project can do specifically. Provide context and add a link to any reference visitors might be unfamiliar with. A list of Features or a Background subsection can also be added here. If there are alternatives to your project, this is a good place to list differentiating factors.
## Badges
On some READMEs, you may see small images that convey metadata, such as whether or not all the tests are passing for the project. You can use Shields to add some to your README. Many services also have instructions for adding a badge.
## Visuals
Depending on what you are making, it can be a good idea to include screenshots or even a video (you'll frequently see GIFs rather than actual videos). Tools like ttygif can help, but check out Asciinema for a more sophisticated method.
## Installation
Within a particular ecosystem, there may be a common way of installing things, such as using Yarn, NuGet, or Homebrew. However, consider the possibility that whoever is reading your README is a novice and would like more guidance. Listing specific steps helps remove ambiguity and gets people to using your project as quickly as possible. If it only runs in a specific context like a particular programming language version or operating system or has dependencies that have to be installed manually, also add a Requirements subsection.
For the DMA configuration, the makefile uses the generate script provided as part of the IP. The makefile uses the $ARM_IP_LIBRARY_PATH environment variable to find the IP, you will have to make sure this is pointing to the correct location in your system.
You will also have to copy the socrates/dma350/config/address_amp_m1_example2.sv
## Usage
Use examples liberally, and show the expected output if you can. It's helpful to have inline the smallest example of usage that you can demonstrate, while providing links to more sophisticated examples if they are too long to reasonably include in the README.
## Support
Tell people where they can go to for help. It can be any combination of an issue tracker, a chat room, an email address, etc.
To configure the IP, you can use the makefile at the top of the repository just run:
`make all`
This will first make a socrates project and then configure the NIC400, BP140 and DMA350
## Roadmap
If you have ideas for releases in the future, it is a good idea to list them in the README.
## Contributing
State if you are open to contributions and what your requirements are for accepting them.
For people who want to make changes to your project, it's helpful to have some documentation on how to get started. Perhaps there is a script that they should run or some environment variables that they need to set. Make these steps explicit. These instructions could also be useful to your future self.
You can also document commands to lint the code or run tests. These steps help to ensure high code quality and reduce the likelihood that the changes inadvertently break something. Having instructions for running tests is especially helpful if it requires external setup, such as starting a Selenium server for testing in a browser.
## Authors and acknowledgment
Show your appreciation to those who have contributed to the project.
To run the cocoTB tests, run `make` from the verif/ directory.
## License
For open source projects, say how it is licensed.
## Project status
If you have run out of energy or time for your project, put a note at the top of the README saying that development has slowed down or stopped completely. Someone may choose to fork your project or volunteer to step in as a maintainer or owner, allowing your project to keep going. You can also make an explicit request for maintainers.
A joint work commissioned on behalf of SoC Labs, under Arm Academic Access license.
For access to the ARM IP you will need to contact ARM directly
