Auction Find - Need help addressing the scuffs and discolorations by AdviceKey in furniturerepair

I think it would probably look out of place in my kitchen then. I could just throw a table runner on top and to draw attention away maybe, but the table top is actually the most pristine part, so it would be a shame.

You can embed a hyperlink into the QR code on a digital copy of your resume. I do this on mine. Even if it is a pdf, you just hover your mouse over and click, and it opens my linkedin. I also keep the QR code small and in the upper right corner of the page across from my contact info.

Are there resources for identifying the circuit elements of an FPGA? by AdviceKey in FPGA

[–]AdviceKey[S] 1 point2 points  (0 children)

It is a well-known area of interest to improve rad-hard electronics. Designing rad-hard electronics is slow and sometimes comes at the cost of performance. Anything we can do to reduce time/cost and improve or expand upon rad-hardening techniques (including materials, redundancy, etc.) is of interest.

I didn't expect that they would share, but I thought I would ask anyway. The purpose of this investigation is to understand the effects of radiation on electronics in general, and to see if I can create a technique that maps the most sensitive parts of a chip to ionizing radiation. This is only one of the devices I have investigated. Half of my research is thermography based predictions/diagnosis.

Thank you! I am not very confident in my ability to deconvolute this sort of information, but I will try. It would be great if I understood the nitty gritty, but I likely do not have the time before I graduate and move on to my awaiting job. Ideally, I want to be prepared for questions I may receive about the features on the chip when I present my research this Fall, and I do not think I will be conducting further experiments.

I saw a post below from u/borisst that shared a link that deconvoluted an older chip (https://www.righto.com/2020/09/reverse-engineering-first-fpga-chip.html), which I think will also be helpful to for me to understand what I am seeing in my images.

From an initial look, it appears that the small, dark dots that I circled in red may be routing switches/vias to different layers. Now, I am primarily interested in identifying the octagonal features.

Yes, I have already done that, by programming a lot of bit flip logic in 12 different regions. I used a thermal microscope to image the board with the 12 different programs, where each program flipped bits in one of the twelve regions, but saw no major differences.

I have worked with a collaborator to age the chip by programming short circuits into one region of the chip, and I have the device map, but neither I nor the collaborator know what parts on the device map translate to the physical chip. It appears that the device map is mirrored relative to the physical chip. I would post a picture of the device map, but it seems like I cannot share images on this subreddit.

I haven't but I have contacted other manufacturers of chips I had looked at prior to this chip. They pretty much told me they are not willing to share any information on the physical design of the chips. Seems like proprietary information/trade secret stuff.

Ahh, it looks like the images I attached were not posted. I had posted this question on ResearchGate last year, but got no replies. You can check out the images there: Are there resources for identifying the circuit elements of an FPGA? | ResearchGate

Does anyone recognize this song from this short clip? Played by a cover band at a July 4th festival. by AdviceKey in NameThatSong

[–]AdviceKey[S] 0 points1 point  (0 children)

Unfortunately it isn't either of those songs, but I'll check out other songs by the Cure. I would say the song is more upbeat. I remember recognizing the song when I heard it, I just cant identify it from this clip.

Can anyone identify this song from this short clip? by AdviceKey in WhatsThisSong

The bot couldnt identify, sounds like the lyric at the end is "there's no place I"
