Quick! 🤞 it'll come DRC clean

🤞

Is there a list / view of the final project list that made it ?

i'm also keen to know what projects made it into the shuttle

yeah something like that one for run 1 https://github.com/wafer-space/ws-run1 would be awesome

I'm sure @Leo Moser (mole99) will generated a https://github.com/wafer-space/ws-run2 once we have everything confirmed with GF.

Absolutely. First, we need to confirm that our reticle is manufacturable. Afterwards, I'll create the repository for ws-run2.


[2026-07-17 7:48 a.m.] 246tnt
What kind of time frame does GF usually take ?  ( like ... a day, a week, a month )


[2026-07-17 7:49 a.m.] 246tnt
Also does the final layout use 2 half rows/cols ?


[2026-07-17 7:57 a.m.] mole99
We are actively communicating right now, but it depends on the issue.

For the ws-run2 shuttle, we added these additional cuts.

Huh, but in that diagram it looks like you're cutting in the middle of full size projects ?


[2026-07-17 8:03 a.m.] sudonet
it sure does


[2026-07-17 8:12 a.m.] rebelmike
So 9 quarter slots, 18 1x0p5 and 9 0p5x1?


[2026-07-17 8:13 a.m.] rebelmike
Plus 18 full size


[2026-07-17 8:13 a.m.] sudonet
looks like it


[2026-07-17 8:13 a.m.] sudonet
if that cut is intentional


[2026-07-17 8:14 a.m.] .leonmc
Why is that surprising? It wouldn't make much sense to add a cut on top of an existing cut.


[2026-07-17 8:14 a.m.] sudonet
fair point


[2026-07-17 8:15 a.m.] 246tnt
@Leon I would have expected the image underneath to use the right size of projects for the tiling. So actually show 9 quarter slots, 18 1x0p5, 9 0p5x1 and 18 full sizes.


[2026-07-17 8:15 a.m.] 246tnt
Rather than show full size dies sliced in half.


[2026-07-17 8:15 a.m.] .leonmc
Ah, I assumed the image was from run 1, and they hadn't generated a corresponding image for run 2 yet


[2026-07-17 8:16 a.m.] mole99
That number is correct. The image is only for illustration and doesn't yet show run 2 :)

[2026-07-17 8:22 a.m.] sudonet
damn that's a lot of half-heights


[2026-07-26 4:42 p.m.] 246tnt
Did GF accept the reticle ?  Are there still issues being worked on ?


[2026-07-27 5:54 a.m.] mole99
There were some minor DRCs which we were able to waive. The mask is currently being generated.

@Leo Moser (mole99) Was any of those in TT ?  If there are things in the common infra, I'd fix them for the next runs if possible to avoid having to waive them.


[2026-07-28 6:49 a.m.] mole99
@tnt As far as I could see, they weren't in the TT infrastructure.

Our insight into the DRC violations is limited. We get a DRC report from GF with a list of categories that were violated and one or two screenshots of examples in the layout. But no actual markers with coordinates.

However, it's sufficient to determine which of the DRC rules still need some work in the open source DRC deck.
