wafer.space Community - FWIW - We delivered the GDS for Run #2

6:23 a.m.

Quick!

it'll come DRC clean

6:31 a.m.

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

GitHub - wafer-space/ws-run1: wafer.space GF180MCU Run 1

wafer.space GF180MCU Run 1. Contribute to wafer-space/ws-run1 development by creating an account on GitHub.

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.

What kind of time frame does GF usually take ? ( like ... a day, a week, a month )

7:49 a.m.

Also does the final layout use 2 half rows/cols ?

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 ?

it sure does

So 9 quarter slots, 18 1x0p5 and 9 0p5x1?

8:13 a.m.

Plus 18 full size

looks like it

if that cut is intentional

Why is that surprising? It wouldn't make much sense to add a cut on top of an existing cut. (edited)

fair point (edited)

@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.

8:15 a.m.

Rather than show full size dies sliced in half.

Ah, I assumed the image was from run 1, and they hadn't generated a corresponding image for run 2 yet

That number is correct. The image is only for illustration and doesn't yet show run 2 :)

damn that's a lot of half-heights

Did GF accept the reticle ? Are there still issues being worked on ?

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.

@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.
