Can i add custom chip art on the top and bottom right corner ( similar to the wafer space logo and qr in the left ) ? Or can i only add inside the pad ring ?

yep, you can! I have a little image on the bottom right of mine. I think the top right may be reserved for an arrow this time around (to help the wirebonding alignment) so I think we can't use that corner

Hey sure got it thank you much Will use only the bottom right

You are also free to replace the wafer.space logo on the top left. The precheck only checks the bottom left and the top right, if you have CoB enabled.

hah, I was skimming an old Adapteva parallela forum post looking for something and saw @tnt. Guess I shouldn't be surprised

@BreakingTaps Good old times

@BreakingTaps It was mentionned at FSiC last year but ... Not really open. If you look at it there is not much there. You get a standard cell library but only abstract view, no GDS. No DRC rules or any device simulation model. So you can "assemble" a chip with purely digital design but nothing more, nothing custom, ...

So you can do basically the same you can do with a FPGA.

ah, welp

maybe some day we'll get a 50-65nm open PDK

I'll just leave this here.... -# Sometimes I feel I should not be allowed to use tools

It's DRC clean btw

haha that's amazing. i can't imagine making it DRC clean too

Next week at FSiC 2026, we'll be introducing the latest updates on the ics55 pdk, eda tools, and design platform, etc. We have also upgraded the ics55 pdk from tier1 to tier 0. Moving forward, we're planning the roadmap, restructuring the repo based on sky130, gfmcu180, ihp130, and will be gradually releasing the remaining files over the next some months.

Maybe we should indeed re-evaluate your permission to use tools

Are you connected to ics55 in some way?

Yes, we have integrated the ics55 pdk to ECOS Studio, but now it can only generate partial gds because of some key files haven't be released, so we need to do some works (like DRC/LVS/PEX) by ourselves.

I read the IHP's slide at the FSiC 2026, their pdk and open mpw shuttle is fantastic, so we will learn from ihp sg13g2, to port more open-source eda tools to ics55, and release remaining data as soon as possilbe.

And "EuroCDP Open-source PDKS and EDA tooling recommendations" book also give us great help-a good comparison table.

There was an attempt at compression ...

Has anyone figured out an easy way to do GDS art?

at least the size went down and not up!

Pixel art in magic

... Okay there might be simpler ... (edited)

Have a look at the FSiC talks from last year, there was one on how the pulp team do their art
