I'm super excited to see if this and Tholin's custom cell library work to see if my club can speed up our project 👀 [2026-10-02 2:10 a.m.] anfroholic Not sure, but here's the list of projects https://tinytapeout.com/chips/ttgf26a/ https://tinytapeout.com/chips/ttgf26b/ {Embed} https://tinytapeout.com/chips/ttgf26a/ Tiny Tapeout GF 26a - Tiny Tapeout 95 designs {Embed} https://tinytapeout.com/chips/ttgf26b/ Tiny Tapeout GF 26b - Tiny Tapeout 90 designs [2026-10-02 6:15 a.m.] 246tnt TT on run 2 have Staf's sram generator yes. {Reactions} 👍 [2026-10-02 6:16 a.m.] 246tnt There is also a couple of project using Tholin cell but it's a known buggy version with internal short so those project are disabled. [2026-10-02 5:48 p.m.] glaxus_ Is Tholin's custom cell library proved out in silicon yet? [2026-10-02 7:45 p.m.] 246tnt @glaxus No. [2026-10-02 7:47 p.m.] 246tnt I think some projects on run #2 use it, but the wafers are barely out of the fab, it will take some time before they get finalized / bonded / sent out ... and then the people with such design still need to test them and report the resuts. {Reactions} 👍 [2026-10-09 12:08 a.m.] glaxus_ I have another related question, how much confidence is there in the 3.3 V SRAM macros? I think it’s at least been proven out once in silicon 2 but wanted to know how many other projects were using it [2026-10-09 7:22 a.m.] rebelmike I might have missed something, but I don’t think there’s been more than a basic check of functionality on a couple of run 1 dies. A number of run 2 projects use it though so there should be significantly more confidence before the run 3 deadline. Until run 2 testing starts, I think this is still accurate: https://discord.com/channels/1361349522684510449/1532458465379750028/1532694419164233878 {Reactions} 👀 [2026-10-15 5:16 a.m.] namibj I'm looking forward to getting a bond tester unit with a "programmable precision voltage supply" add-on "dongle" (the dongle made and ordered; the tester with the dongle programmed) to do retention (and with it, power-up-bit-pattern) tests on some of the dies (especially if I can get the dongle to someone who has a bond tester unit and access to a bunch of the dies and time to cycle a few dozen through it (technically should only take like 5 minutes or thereabouts at a single temperature)). That's for FlexMem, Stef's SRAM generator. Technically that covers 5V and two DRC variants of 3.3V SRAM. And it's pretty much the densest flexible/varied SRAM we have access to without signing any NDAs. {Reactions} 👍 [2026-10-19 3:11 a.m.] glaxus_ Started a thread. [2026-10-19 7:38 p.m.] 0xaef @proppy we use XLS for datapath blocks on gf180mcuD and would like to upstream a GF180 delay model (run_op_characterization.py on the foundry 7-track cells) once our library qualification wraps up mid-November. Would a PR to google/xls be the way to go, and is anyone already on it? [2026-10-20 10:17 p.m.] rebelmike Where is best to report a DRC error in a standard cell? This is in the foundry 9t5v0 mux4_4 cell. Error is `Poly overlap of contact < 13 (CO.3)` [2026-10-21 12:11 a.m.] bailey8889 Maybe here? https://github.com/fossi-foundation/globalfoundries-pdk-libs-gf180mcu_fd_sc_mcu9t5v0 {Embed} https://github.com/fossi-foundation/globalfoundries-pdk-libs-gf180mcu_fd_sc_mcu9t5v0 GitHub - fossi-foundation/globalfoundries-pdk-libs-gf180mcu_fd_sc_m...
