I should start working on my new designs in earnest I guess! A lot sooner than I was thinking for some reason...probably best not to repeat the frantic finish-in-one-month sprint like the first run 😅

I have a spreadsheet @ https://docs.google.com/spreadsheets/d/1KD2Mn7s7WoZ738tmH0LNp_uvDCJVLOdqiyMbqEh0ApU/edit?gid=0#gid=0 - but expect dates to change as I have yet to get confirmation for the wafer out date from GF.

That's a good resolution, but it never works out. In practice, you always end up making last-minute changes 😆

Did GF confirm fab out now ?


[02/10/2026 23:26] polyfractal
😭 😂

I /think/ I got the wafers out late date yesterday but I won't be able to confirm until Monday that is what the date provided actually is.

In Run 2, will there be an opportunity to purchase larger slots than 1x1, like 2x1 or 2x2? Or would it mess up all the dicing/sorting?


[02/17/2026 21:58] mithro_
They do mess up the dicing / sorting. I have been focusing on smaller slots. Do you actually have the funds for bigger slots?


[02/18/2026 12:01] thorben_61995
That's a pity. Yes, we have funds for bigger prototypes and the 1x1 slot could not fit everything that I wanted. But of course I understand that it makes limited sense to accomodate larger slots if only one person is interested... Anyone else in need of more area in future runs?


[02/22/2026 02:15] mithro_
What was your limit? There is plenty of work to improve things like typical place and route density and such


[02/23/2026 16:06] thorben_61995
I already had a utilization of 65% with >400k standard cells (w/o the macros) and it fit about half the logic I wanted, so PnR improvements won't get me there. Proprietary synthesis would probably compress the logic quite a bit, but working with proprietary tools is not an option for this project. Except for larger slots I currently don't really see a solution. If it helps, I think we would be able to pay a reasonable premium for a larger slot and would not necessarily need as many samples.

Options I can think off the top of my head are :
* Switch to laser dicing
* Run more wafers and dice those just to separate those particular dies
* Switch an entire row / col to the larger format

Laser dicing would give us a lot of flexibility in mixing different slot sizes.

Who's doing the dicing ATM ? Is it GF themselves ?

@Tim 'mithro' Ansell


[02/27/2026 07:55] mithro_
So far I have not found a cost effective laser dicing place.
