@Tim 'mithro' Ansell can you help me figure out what mask is the top layer of MPW-3 - both files on your system and green label on the mask box

5:39 p.m.

GF MPW0 (or o?) #9 - was this a google run?

There where I think two Google MPW runs done with GlobalFoundries

@carlfk - https://foss-eda-tools.googlesource.com/third_party/shuttle/gf180mcu/

1:21 a.m.

@carlfk - The top layer would be the pad frame, what you probably want is the top metal layer which is what is the most visible thing?

1:22 a.m.

@carlfk - That mask would be MM5 I think? https://big-storage.welland.mithis.com/sky130-masks/masks?run=mpw-004&mask=MM5

1:23 a.m.

@carlfk - What does VCF mean?

Vintage Computer Fest - where I am promoting w.s this weekend

2:20 a.m.

I figured this out a few days ago and am putting together an exhibit

"Not generated yet." did you hit Generate or should I hit it?

2:24 a.m.

I hit it - requested — the worker renders one mask at a time; this page reloads every 15 s.

2:28 a.m.

@Tim 'mithro' Ansell What is the interesting mask for MPW3?

@carlfk - FYI, you don't have the masks for MPW3, I do....

oh. I thought I did.

I'm pretty sure the sky130-masks tool says where each mask is now? (edited)

I see that now - I thought I was getting 3-8, or 3-something but maybe that changed once someone tried to pull it from storage?

https://big-storage.welland.mithis.com/sky130-masks/ids

2:52 a.m.

@carlfk - Or maybe I'm a programmer and have off-by-one errors all the time?

I have MPW 1, 2 & 3 here in Adelaide

is this GFMPW0 #4 == mpw-004 ?

Never mind - GF = Global Foundries so there is no way I have any masks for that wafer

we have mask display thing.

@carlfk - Jeff Geerling might be there? https://www.youtube.com/watch?v=CivRNW0b1H8

Jeff Geerling

I modded a 30-year-old GPS Time Server (Telstra should've)

neat - pretty sure he was there last year and posted somethig about Peter's SEM

@Tim 'mithro' Ansell can you get me an image, svg pr png, of ws run1 reticle / one maks/ whatever is quick n easy

12:25 a.m.

something that shows each die is a different design

is there an svg version? I would hope is smaller

@carlfk - I'm sure you know how to use image magic or gimp to make a smaller version of an image. You have a whole pipeline which does stuff like that.

There seems to be a lot of text overlapping qrcodes from what I can see?

I think I will make the project titles bigger - the point of all of this is to attract attention as people walk by, not provide details

That is why the US paper format is bad -- with the A series, you can just rotate them by 90 and put them next to each other.

How does that look? Terrible?

Cool microscope setup

15 min into the event and I've already got two people that want to check it out more.

@carlfk - Is/was VCF a one day event or are you there now?

2 days, just ended, I'm packed up and home
