The conference doesn't start for a few more hours but WOOT '25 papers are up!
I'll be presenting "Extraction of Secrets from 40nm CMOS Gate Dielectric Breakdown Antifuses by FIB Passive Voltage Contrast" later this morning.

The paper right before me, which I also contributed to, is "Security through Transparency: Tales from the RP2350 Hacking Challenge"
Anybody have a USB superspeed 2 port hub chipset you like?
No PD required, but if it includes the muxing for USB-C rotation that would be great.
Single row QFN package would be ideal, large (0.8/1mm pitch) BGA doable. TQFP and WLCSP/0.5mm BGA are no go.
Just ordered the respun STM32H750 test board for the Trion T20 devkit.
Hopefully I didn't have any *more* monumental screwups here.
In the meantime, I still have the RGMII test board that I haven't had a chance to assemble and test. Maybe I'll get to that during the week, I have some other stuff to clear out first...
Was up until 3AM poking at stuff.
I need to be up by around 5AM on Monday in order to make it across the water to WOOT in time to not miss the opening talk (and give my presentation right after it).
This is going to be fun.
What is it with people washing their hair with sham poo?
I mean, I guess it's better than using real poo, but wouldn't soap do a better job?
Dear IC designers using poly for local interconnect between adjacent standard cells: could you please not? It makes standard cells more annoying to pick out since things don't all look the same and not all poly is part of a cell.

I'm gonna say this is probably as good as it's going to get. In 5200 sec it drifted in phase by 146 degrees.
That's 7.78-5 Hz beat frequency (0.0778 millihertz) or a frequency error of 7.78e-12 .
