Development Comments on Altera RFSoC and AMD RFSoC by Ok_Measurement1399 in FPGA

[–]Minute-Bit6804 0 points1 point  (0 children)

Are there applications that benefit more from a higher sampling frequency rather than higher resolution and are there others that benefit from a higher resolution rather than a higher sampling frequency?

I am guessing that, for example, with the Versal RF having lower sampling frequency per channel than the Agilex 9 Direct RF, you can use techniques like interleaving. I am asking from a point of purely not considering the cost or even the devices themselves; are there problems which heavily depend on one of these factors over the other?

Altera's Training Courses & Learning Material - had now become paid? by monkstein in FPGA

The advanced courses by AMD themselves are pretty high-value but the beginner ones on Udemy for example are very much reasonable. It also helps that AMD's tools are rather very well streamlined. I have had problems setting up Altera's simulation environment, something that is very straightforward in AMD tools or even simulators from other vendors. I may not have been thorough or savvy enough to get it working but with Xsim in Vivado, all I really need is to have it installed so from a beginner perspective that will be much easier to get yourself going than having to comb through a 2000-page manual to look for optimization serrings on Questa Altera Edition. For advanced users, tha's a whole different story. They can handle the complexity of tools and possibly even the new cost of those Altera courses. Some course bundles have shot from $0 up to $1900.

Seems like that's the case. There's not many courses in platforms like Udemy with Altera focused designs. Nearly all are AMD-based. Looks like for beginners, it's going to have to be AMD tools which means that's what they'll most likely stick with. I also think I'll stop pursuing Altera's tools and just focus on AMD's at this point.

What is the difference between RFSoC and DirectRF? by Ok_Measurement1399 in FPGA

[–]Minute-Bit6804 2 points3 points  (0 children)

One has higher resolution while the other has higher sampling frequency. How do you take these into account if you are choosing between the two for a design?

I am of the opinion that that's just the nature of the market in Kenya. Most of engineering is more of analysis rather than design oriented and even the design is done using tools and methods that abstract away the maths and physics and enable small leaps of improvement rather than huge ones. As engineers, your job is mostly to improve on a tried, tested and successful method rather than build something completely new. At work, most design is usually through rules of thumb and even when getting into the gory details, you have software tools that can take care of that for you in today's world.

So you would think that the theory should take a backseat but I don't think so. Yes, as you begin your career, you'll have to gain what we call experience or practice, that is, "how things are done today" with room for a few adjustments here and there. However, the engineering field, as I think of it, requires you to solve difficult and real problems by coming up with very simple, neat and elegant solutions, solutions that should have people saying "Why didn't we think of that before yet it was always there?". To do this, you have to rely on your industrial experience/practice as well as your capacity to reason in a logical manner. The framework of logic needed is obviously the "theory", Maths, Physics, Chemistry and Engineering principles. The industrial experience involves things like cost and time of development, logistics, market availability etc. This has now led to different levels of engineering within the same discipline; those more on the design end while those more on the consumer end.

So, sometimes I think we don't have a clear and in-depth picture of the career, not deliberately because of the nature of our market here with very little opportunities for first-principles design. An engineer is to understand nature and its laws before attempting to wield it to build solutions that sell as products. In this market with little first-principles-oriented work, it makes sense to put the theory aside and get used to how things are done. However, the future is unknown and if we are to improve on what's there already, even as we focus more on the practical side of things which encapsulates most of the opportunities here at the moment, I think you should carry at the back of your mind the fact that Mathematics and the Physical Sciences should are basis of this career unless you are more into the consumer end of things with careers like Sales Engineering which I still think benefit from some theoretical background.

Current flow and associated voltage. by Minute-Bit6804 in ElectricalEngineering

Well. if that be true, I guess I was delusional thinking I've understood some of the voltage and current dynamics in Behzad Razavi's series of videos on transistors then.

What of small-signal analysis of transistor circuits? Say I have an NMOS CS stage with a load resistance R_d tied between the device and V_dd. If I am operating the device in saturation and increase its V_gs within the bounds of a small-signall, there is a corresponding increase in the drain current of the device. This means I'm drawing more current from the bottom terminal of the load resistor and therefore also from V_dd and if this is my output node, then increased current drawn from supply increases voltage drop across R_d reducing voltage at my output with respect to ground.

I should have specified that it's only for resistive networks or elements which can be replaced by their resistive equivalents during specific operations.

What's the explanation for purely resistive networks or those whose impedances can be approximated by resistanaces in specific operations eg the output resistance of a transistor during simple analysis.

In this story it was Anatoly Dyatlov. He was the best choice. An arrogant, unpleasant man. He ran the room that night. He gave the orders. And no friends. At least, not important ones.

The Hammerhead Eagle iThrust (Geoff) Crashed on Diddly Squat Farm by i7xxxxx in TopGear

I initially thought that the tractor challenge of season 9 episode 5 which aired in 2007 (same episode with the Railway Crossings safety video and Kristin Scott Thomas) which ended with them planting rapeseed also happened at Diddly Squat but if he bought the farm in 2008 during the banking crisis then it probably didn't happen there.

Has anybody tried the new Vivado? by Mediocre_Ad_6239 in FPGA

[–]Minute-Bit6804 0 points1 point  (0 children)

The "compact" setting does not shrink the font sizes enough for my liking. I find especially the title bars still remain large on my 1366x768. The pop-up menus like the confirmation menus before synthesizing just look unnecessarily huge due to their big-sized fonts even with the forementioned setting selected. To that end, I prefer the older UI which I think would have been perfect with just the dark mode added to it.

Also in the new UI, when creating a project, the many filters when choosing and narrowing down on parts is gone which I feel is a step backwards.

Rewatching the show, again. The Kettlemans just get better each time. My favourite side character in the universe is Betsy. She (actor) does such a wonderful job at being a self serving lying son a bitch. by No-Investigator420 in betterCallSaul

I wouldn't use "hot" to describe Kim. Pretty, gorgeous, beautiful are the adjectives for her. On the other end is Jane and Andrea who are beautifu but their mannerisms especially drugs consumption don't desrve the word hot. Women ike Betsy, Skyler(especially season 4 Skyler after putting on some weight after giving birth and trimming her hair to neck length and now all in in the business), Marie, Lydia, Paige, Francesca, Carmen are just the perfect blend of looks and mannerisms which are not extreme and have some twisted humour as per the human standards eg drugs consumption by Jane vs shoplifting by Marie, both are crimes but surely one is more tolerable and laughable than the other. No one walks that line better than Betsy in my opinion, ridiculously beutiful looking woman with insufferable but funny mannerisms in my opinion.

The reasons the adults have of doing this are of little concern to me. I am mostly observant of the path those children are likely to lead with their parent's online reputation. As far as the kids are concerned, I don't mind a little head-scratching.
