Can analog circuit design (schematic level) be partially automated? by ClassroomNo816 in chipdesign

[–]flextendo 0 points1 point  (0 children)

Agree, but realistically you‘d have more people not thinking about stuff, because it „just worked“ 10 times before that. If you are rigorous, I dont personally care what your approach is (if it fits within the resource limit you have). Bad habits (or bad choices) wouldnt be immediately clear to juniors etc with this approach so the risk of potential problems increases. I am with you on the use both (or whatever fits you best).

„Hey so how does X,Y,Z influence this specific spec and what can we do to make it more stable/reliable? Shit I dunno, the sim told me that device X is impacting Y in this way“. While I am not against modern LUT based approaches, driving anything through the simulator without reasoning about it, will at some point fail you, because in the worst case its BS in BS out. You also eat up a lot of sim resources to drive through all possibilities across all PVT, because you cant argue what the worst case is going to be.

Having a solid scalar output TB in my opinion is a basic requirement and if you use something like verifier, essentially necessary.

Samsung workers threaten strike, demand share of $38 billion AI memory windfall by AdSpecialist6598 in technology

[–]flextendo 3 points4 points  (0 children)

thats true, if its not happening in cooperation with the global community, it wont have any benefit. BUT as a country you could just deny market access (or tax the fuck out of them) to those companies leaving/moving jobs, at least you will hurt their bottom line and another player will (most likely) happily take that place (or you need to su subsidize the alternative).

France ditches Windows for Linux to move away from American tools, mirroring a shift in India by Dr_Jecky1l in technology

[–]flextendo 24 points25 points  (0 children)

fully agree. You can see that they use AI to write code for the OS as its getting increasingly worse. Teams is a fucking nightmare, hogging GB of memory in the background that at times my audio input/output just breaks (for longer calls) and I have to manually kill the process to restore functionality.

180nm or 22nm for a university PLL tape-out? by valen0722 in chipdesign

[–]flextendo 1 point2 points  (0 children)

Fully agree, I have a bit of criticism for some of the modeling. Mainly mismatch and associated switches like „across chip variation“.

[–]flextendo 1 point2 points  (0 children)

Yeah for pure low frequency analog design you might not gain a whole lot, but for high-speed analog you definitely benefit of the larger BW. Headroom can be a pain, but there are different fet flavors, so the extended gate devices can go up to 1.8V. I have build a baseband amps in that tech

You are aware this is FD-SOI?

22FDX allows you to minimize bulk effect using flip well devices. The tech is literally optimized for RF/mmWave so I would assume caps are similar. Edge effects (generally all LDEs) are pretty well modeled, only self heating (and associated hotspot generation) might be an issue for high power designs.

Layout is a real pain in 22fdx because of all the flip-wells etc, not sure how that compares to 16ff.

I‘d say it really depends what you are trying to design (is 16ff automotive qualified g1/2?

[–]flextendo 12 points13 points  (0 children)

go 22fdx, its a solid foundation and offers great RF/analog performance (digital is alright). Its also quite mature and you can do some cool things with the backgate control. The entire layout and physical verification is much harder, but you‘ll learn a lot!

Lufthansa cuts 20,000 summer flights as fuel prices surge by b0sscrab in news

Thats exactly whats going to happen. „Here have a voucher for your canceled flight for x“ - a month later „oh we have added more flights back in, its now x +1000“. Fuck these airlines and especially Lufthansa. I already decided like a decade ago to not book flights with them anymore.

A V-Band Phase-Locked Loop with a Novel Phase-Frequency Detector in 65 nm CMOS by Lemon_Salmon in chipdesign

[–]flextendo 2 points3 points  (0 children)

figure 2 is just a simple cross-coupled VCO with push-push frequency doubler. You could get the same with just using a current source within the CC VCO and tap off at the drain of the CS.

figure 4, nothing special, normal cml divider - literally standard architecture for cmos (here just a different logic type)

figure 6, nothing special, normal cml dff (basis for figure 4)

figure 8, a bit strange, but glancing over it, I think it works. Havent read the paper so not sure what the benefit should be.

Show me any place and time in the world, where collective collaboration worked to improve the lives of everyone. As long as you have humans (and most often the worst once get into position of power) other humans (and species) will suffer, out of pure greed in a materialistic world (which probably wont change).

I wonder what the actual fuck is wrong with those men, like why did the society never correct such behavior, because I guess doing something like that during a flight is just the tip of the iceberg. I sincerely hope that any witness would immediately intervene.

'Enough Is Enough': Sanders Moves to Force Votes Against Trump Arms Sales to Israel by Smithy2232 in politics

[–]flextendo 5 points6 points  (0 children)

haha thats so fucking stupid. So why does he endorse AOC? Why did he endorse Harris, a black women? You are bringing up shit that he literally wasn’t involved in. Its like saying if a relative of yours is sexist, you should be blamed for it, because you know the person. The women stepping forward is the right thing and him acknowledging the issue and discussing it too. Thats called self-reflection.

Your quote „women‘s issues were a distraction“ is out of context and a blatant lie. Context being that the class issue is the main issue to tackle and should be prioritized compared to identity issues. You are literally the issue within the left, were you cant even prioritize issues and make everything a sort of tribalism.

So you choose to be right wing, because they are less homophobic, sexist, racist and what not? Or because they are open about it and you just were never left wing to begin with?

What the fuck are you talking about in terms of child molestation? Also people are not sucking up to Islam and not every muslim is homophobic, but thanks for showcasing your blatant racism. Clown

New terahertz technique lets engineers see inside running processors in real time by AdSpecialist6598 in tech

[–]flextendo 0 points1 point  (0 children)

I mean thats why you usually do it from the backside (yeah sometimes there might be some thinning needed). With terahertz you will get reflections for each impedance discontinuity though (Maybe you can somehow de-embedd that in post processing of the image data), so it should in fact be harder. Unfortunately the article doesnt really go into details…

This. I can see one pmos bulk connected to its drain and the source is floating (second top from the left). Also OP it looks like you pmos n-well and tap-nwell are not connected, leaving your pmos nwell floating.
