I don't recall how the timeline of Openlane 2 and the MPW programs ended going [06/01/2025 20:33] Deleted User I don't believe so, no.

I joined recently and I just realized I should maybe introduce myself for those that don’t know me yet. I’m here because I have a lot of experience with GF180MCU from my three submissions to GFMPW shuttles (one of which was a multi-project die), and a lot of tapeout experience overall. I want to help however I can, considering how much time I’ve spent working with gf180. And am also just excited to get to make chips again using this PDK. {Reactions} 👋 (2) 🎉 [06/19/2025 12:54] tholin I may actually be interested in making a custom standard cell library for gf180, just as I have for sky130. I took a look at the 7 track cells in magic, and I see room for improvement, I think. [06/25/2025 10:48] tholin After a little bit of fighting with gf180mcu’s oddities, I was able to extract, simulate and characterize one of the 7-track standard cells with magic, SPICE and lctime. So it looks like my usual workflow can work here. Well, ignoring the fact that the output values of my characterization are up to 50% off from whats in the PDK’s liberty files. Still investigating this. {Reactions} 👍 ============================================================== Exported 19 message(s) ==============================================================
