Hi, My Libresilicon Testwafer design that was planned for the first Google Shuttle run was unfortunately moved due to DRC issues in our standard cells from the first shuttle run to the second shuttle run, somewhen mid 2021. This is my design test-wafer design: https://github.com/thesourcerer8/carav el-stdcelllib-stdcells/ There are 5 more shuttles planned, so for anyone who is interested in creating additional projects for the Sky130 process, I have collected a list of videos and important links that explain Skywater, the Caravel Management frame, Openlane the RTL2GDS flow: https://docs.google.com/spreadsheets/d /1fM301JZe_2h0- mTfyahFGRWqt3fDhnnSe2X3_pM5GKI/ Best regards, Philipp Gühring

OK. That happened (Funding)

Hi folks So on Wednesday, 10 am Portuguese time, I'm having a ZOOM conference with the other folks of the Photonics lab at INL, where I'll be showing a presentation I'm right now tinkering together. The goal is to use LibreSilicon in combination with their Integrated Photonics, in order to build neuromorphic chips. By becoming part of Jana's research project (she's a professor for photonics at INL), she and I can make LibreSilicon part of the university projects which would make it subject to direct EU funding. Just a heads up. Cheers -lev

Libresilicon status & PR
by Ferenc Éger 16 Dec '20

Hello Everyone, I just went across this reddit post on Libresilicon project: https://www.reddit.com/r/chipdesign/comments/kcjfo9/thoughts_on_libresilico… Basically, there are two major points visible here. First: it sounds if it were a necrolog for the project. Based on this, it seems our third-person public image is that we are still in an university lab in HK, not showing any progress or result in the past 1-1,5 years. Is it possible for us to counter this argument somehow, and put that on some visible place (e.g. the twitter account or on the website)? Back in 2019, the time the project moved to INL, there was a plan to make some sort of "legal entity" to interact with NLnet and INL. What is the status regarding this? Second, it seems that the final objective of the project (developing the tech node and selling ICs (Arduino clone, 555, SoC, ...) made on it, or providing the fabrication as a service, or just develop the node and leave it floating, or selling the maskless stepper as a product, or whatever) and how the project wants to reach it is not entirely clear from outside. I think this needs to be addressed and clarified. @David: Were you able to take contact to JBD? What is the status of the microscope-stepper system? Is info on it is public, or it is the private attraction of INL? Regards, Ferenc Éger

libresilicon.com domain sinkholed
by Éger Ferenc 14 Nov '20

Hello David, Sorry for spamming all 4 addresses I know, I just wanted it to make sure you received it due to the subject above. >From Hungary and Germany at least, it seems that the secondary DNS provider "buddyns.com" is sinkholing both lanceville.cn and libresilicon.com domains by replying 127.0.0.1 to all requests. The libresilicon website, git, the list server and the mumble server all are affected. I managed to access them by manually digging the IPs starting from dns.lanceville.cn's glue record in the chinese DNS, but ... Regards, Ferenc

Update

Hi everyone So I had some beer with a professor from INL, she's doing Optronic design, ranging from building quantum CPUs to treating cancer. Besides having a pleasurable two hours, she also advised me on how to approach INL and offered help in establishing contact. I also discussed with her the mask less stepper aligner idea and INL would most likely be taking one. I also have talked to Mohamed and discussed with him the mask less stepper aligner idea as well, he can put me into touch with Skywater, as soon as I'm done. In order to avoid mechanical deformation which might bring the aperture out of focus due to thermal expansion, I decided to manufacture the machine from Aluminum Oxide, an industrial ceramic which is harder than steel. I think the rigidity of the material is acceptable, considering that it will be a stationary machine in a clean room. On Sunday I can't make it to the Mumble session BTW, because I'll be on a bus ride to another city, to visit the parents of a friend for a few days. Cheers -lev
