Keybase
by Éger Ferenc 23 Apr '20

23 Apr '20

Hello Everyone, I "just" received (actually on Apr. 13, but I did not log in to my mail since then, so I just read) a notification from "Keybase" that "Lawson English" invited me to a "libresilicon" team. Did anyone got similar mail, or can anyone confirm if it is not a scam? BTW: @David: I wasn't in Jitsi (sorry for that), can you please wrap up shortly what the heck happened? Regards, Ferenc

LibreSilicon foundation
by David Lanzendörfer 22 Apr '20

22 Apr '20

Hi everyone So, since there is still NO LibreSilicon foundation, I've decided, that I'll probably just incorporate it myself, where I am right now, in Portugal. For 375€ I can register the LibreSilicon foundation within two weeks, by going to this office here: https://www.irn.mj.pt/sections/irn I'll pay this fee from my own wallet. Two people will have to be present, so I hope Hernani and I can do that together, when he comes visiting me, after Corona Chan is done here, especially, because I could really use his help with the language. Does anyone have a problem with me incorporating the LibreSilicon foundation in Portugal? Cheers -lev

Warning: Don't hand out your MoU
by David Lanzendörfer 21 Apr '20

Hi all Another thing. I don't know, whether Devon still is talking with Merik, but in case he comes and asks you for your MoU, don't hand out a copy! I don't know exactly what his plan is, with those MoUs, but better don't risk anything. Cheers -lev

Mumble meetings + Warning
by David Lanzendörfer 21 Apr '20

21 Apr '20

Hello Little heads up: Better try to avoid that Jitsi room where that Merik is hanging around. I checked with NLNet, and some other sources I have, and it turns out that his stories are just fantasy. I don't know... Smells like a con artist, I just don't know yet, what his scheme is, but I already had to deal with a con artist a while ago, who also wanted to leech on the financing I was trying to raise for LibreSilicon... I removed all of Meriks email addresses from this mailing list and deleted his libresilicon mail aliases I had borrowed him for a few days. Lets hope there hasn't been any damage done yet. I'd say, we either switch back to Mumble or could use the integrated Jitsi session feature in Riot. What do you think? Cheers -lev

Hello everyone A quick question to everyone, who has applied for NLNet funding. Did you do so, by associating with LibreSilicon OR Libre-SoC? This question is just to verify. Cheers -lev

Liberty Comparison
by Philipp Gühring 15 Apr '20

15 Apr '20

Hi, Does anyone know a tool to compare 2 liberty files (.lib) ? I would like to get a report of the differences and/or similarities, and perhaps some statistics for min/max values, and visualisation of the tables. I would like to get a report from the tool. Best regards, Philipp Gühring

Maskless lithography
by David Lanzendörfer 12 Apr '20

12 Apr '20

Hi everyone So last Sunday, Ferenc and I brainstormed on how to achieve smaller feature sizes with a UV wave length, which limits us to 400nm or so. We discussed splitting a lower feature size layout into multiple masks and then doing overlapping exposure steps. Ferenc pointed out, that we might run into an offset issue. I've been thinking about this for a while and the solution came to me on the toilet just now, and it's actually surprisingly simple. Since we're using a DMD and not physical masks, we can do the multiple exposure steps all at once, without any stepping in between. while(!eow()) { // end of wafer expose_mask(1); expose_mask(2); step_to_next(); } cheers -lev
