<!channel> Don't miss our webinar with Emilio Isaac Baungarten Leon, the first place winner of our 2nd AI Design Contest! Join us now! https://efabless.zoom.us/webinar/register/7216971450136/WN_kfhz-JPJQjKffqdOaNXlZg AI by AI: Neural Network Design - Exploring AI-Driven Hardware The use of Artificial Intelligence (AI) in Integrated Circuit (IC) design is now a reality. It can be employed at various stages along the IC design supply chain. The talk will describe the development process of the SoC "AI by AI," a Convolutional Neural Network (CNN) created using Large Language Models (LLM), and the downscaling to silicon using the Caravel and chipIgnite programs. What you will learn: - Conversation flow with LLM - Software and hardware development using AI - The journey of developing a CNN from TensorFlow to ASIC

<!channel> Emilio, the 1st place winner of the 2nd AI-Generated Silicon Design Contest, will be presenting his design, "AI by AI." You don't want to miss this webinar on Oct. 19. https://tinyurl.com/e5pf34u7

<!channel> The AI by AI webinar will start in one hour, at 11 a.m., PT. https://efabless.zoom.us/webinar/register/7216971450136/WN_kfhz-JPJQjKffqdOaNXlZg

Awesome AI for EDA https://ai4eda.github.io/

FYI, ChatGPT-plus (GPT 4.0, a.k.a. "the paid version") now has the capability to analyze images. I uploaded a screenshot taken from gtkwave of the output of a VCD file, and ChatGPT was able to perfectly describe what was going on in the image. That includes being able to tell that the gtkwave display had a hierarchical list of signals in the left-side window, that the display was indicating time of simulation and was in the middle of the simulation and zoomed in, and it was able to correctly identify the signal names in the display (with one minor misspelling). This opens up a vast capability to debug digital (and probably analog, and mixed-signal) systems by direct analysis of the waveforms. Amazing.

New paper from NVIDIA that might be of interest to this community: https://research.nvidia.com/publication/2023-10_chipnemo-domain-adapted-llms-chip-design

Hi everyone. I'm trying to submit my project for the CSAW competition but i get the following errors when i try to push my project with

$ git push -u ef-repo main

but it fails with the following error:

<mailto:git@repositories.efabless.com|git@repositories.efabless.com>: Permission denied (publickey,gssapi-keyex,gssapi-with-mic).
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

The SSH key has been added to efabless platform and the same SSH Authentication Keys is on my github account setting. So, I don't know what could be wrong, any idea?

@Emilio Baungarten are you available for a quick zoom call?

We are looking forward to your submissions. Just a reminder that the deadline is only five hours away, 11:59 p.m., tonight (Pacific Time) Thank you!

Apologies for leaving this extremely last minute but does anyone have any tips on how to fix this error when running make user_project_wrapper for the design challenge? Running make user_proj_example completed without errors.

We've had multiple users with a Bad Gateway error overnight and are still working to find root cause (Other than 40 people trying to tapeout multiple times on the same night). There will be a formal response this AM as soon as the west coast team is online but I do expect an extension. (@mkk @jeffdi)

<!channel> Thank you to all who have submitted projects to our third AI Generated Open-Source Design Challenge. We had a server issue on Thursday that affected multiple contestants. In the interest of fairness to all who have worked on their projects and given that the weekend has arrived in much of the world, we are extending the deadline to Monday at 11:59 pm Pacific Time. https://efabless.com/genai/challenges/3

Hello. I got to know about the contest only ydy. Can you pls tell me the schedule for the next run of the contest ?

@Sahil Khan The next challenge will be open again in few weeks. Stay tuned. The deadline will be targeting the April 2024 chipIgnite run.

@mkk Thanks, for the info.

Dear efabless teams, Our team has tried to submit our shuttle to the AI Generated Challlenge. I saw on the web that the guide you guys uploaded on the YouTube link takes about 15 to 20 minutes (). But it's taken us an hour and 30 minutes just for the precheck and we're not done yet (step 9/12). Could this be due to the server being slow? I'm worried we won't be able to finish in time to meet the deadline. Could you guys check the server for us? Is there a way for us to submit on time, or is it possible for us to submit late, or can we submit without doing the precheck, please?

@Anish has left the channel

are any folks here currently at csaw?

missed the presentations in the morning and i wasn't sure where the poster session is

Hi Anish! The only posters currently up for the AI Hardware Attack Challenge are from the three finalist teams who are here in person (the rest were virtual) and their posters are set up along with the Applied Research Competition's. That said, the posters for all of the finalist teams are now shared on our challenge's site: https://www.csaw.io/ai-hardware-attack-challenge

When will we have the result of the contest?

Yet another GPT chip design contest!
