Systems with Specialized Hardware

There has been an error in the calendar (now corrected):

I have accidentally put today's lecture (pipelines) one week back.

I apologize to students who missed the lecture because of my mistake.

Please watch the recording, and if anything is unclear, let me know. We can schedule a session to recover this lecture.

Best regards and enjoy your vacation!

The milestone 2 instructions have been updated with information how to run OpenLane if your machine has less than 16G of RAM.

you need to run:

every time before you run make mount (you also need to run the other export command too)

To allow docker to use swap.

No need to run make again.

To enable the swap on your machine run the following commands as root:

We have released the second milestone today.

You can find the requirement document Milestone2.md on gitlab in the ms2 branch.

https://gitlab.cs.uni-saarland.de/os/swish-24ws/project/-/blob/ms2/Milestone2.md

Today's project session covered how to install OpenLane and how to generate plain verilog for Vortex.

Please see the slides and/or watch the video if you have any questions.

For now don't worry if the synthesis reports any errors.

Hi all, 

Thank you for getting started early on the project assignment and helping me iron out some rough edges! I have made a couple changes to the README where the `make check` vs `make tests` rules were inconsistent with what existed in the Makefile or `sudo` was missing from the chroot command. Please pull the upstream changes from the class main project repo. Some of the changes will fix a broken PERF output for `printf` test.

There was one important factor I overlooked which was committing changes inside the submodule. It is essential that you have your own submodule that you can organise and add branches to, so I have created new submodule repos for you all who registered for the "Project Git Repo" and you should have received an email for it.

Since some of you may have already gotten started, instead of forcibly changing the submodule pointer for you, I have given instructions in the forum. Please see the forum response here. Please ask any follow up questions there. Pointing to your submodule and committing changes there will be necessary for the project milestone 1. Although your private submodules should already have all the necessary files for milestone 1, you should point to the public main submodule repo with

git remote add upstream https://gitlab.cs.uni-saarland.de/os/swish-24ws/project-vortex-swish.git

after which you can use 

git fetch upstream ms1

git merge upstream/ms1

to sync up with new milestones to the submodule. 

Ultimately the gitlab ci/cd will still use your main project repo's `msX-submission` branch so make sure that the submodule is pointing to your `vortex-swish` repo and the correct commit/branch!

Thanks for bearing with the bugs and I appreciate you all for bringing them to my attention!

As mentioned in the previous lecture (whose recording will soon be uploaded), please remember to use the CMS "registration" > "Project Git Repo" so that we can launch a project repository for you with all the basic material. We will go over the project in the first project session which is this week! You will get an email when the repository has been generated.
