555 versus Raspberry Pi Pico: Which side are you on?

October 21, 2024

I’ve seen a lot of engineering religious wars over the decades. Chances are, you have as well. Here’s a very partial list of some wars I’ve seen:

Motorola 6800 versus Intel 8080
Motorola 68000 versus Intel 8086
Microsoft Basic versus DEC Basic
C versus <your favorite programming language here>
Verilog Versus VHDL
AMD x86 versus Intel x86
RISC versus CISC

From Thought to Circuit in Record Time with AI

by Max Maxfield

October 17, 2024

Thus far, if the truth be told, I’ve had mixed experiences with large language models (LLMs) and generative artificial intelligence (GenAI) as personified by ChatGPT. I started, as many people do, by asking ChatGPT questions about things I knew nothing about, receiving responses that appeared to be reasonably impressive.

The reason for my emphasizing the word “appeared” in the previous paragraph is that I next asked questions about things I did know something about, only to discover that many of ChatGPTs responses were missing key elements or, in … Read More → "From Thought to Circuit in Record Time with AI"

Zeke and His Chums Are Poised to Chat with the ISS

by Max Maxfield

October 15, 2024

Good Grief! It’s happened again! I must have blinked, or sneezed, or… hmm… enjoyed a bodacious bowl of beans (let us say), only to find another hunky chunk of time has zipped past under my nose (no pun intended), leaving me dazed and confused in the here and now.

Just to set the scene, deep in the mist of time we used to call 1970, when I was but 13 years of age, I would be found dancing with delight if I managed to make a simple 2-transistor oscillator warble in an annoying way. … Read More → "Zeke and His Chums Are Poised to Chat with the ISS"

NIST Issues New Quantum Crypto Standards for Cyberspace

by Steven Leibson

October 14, 2024

NIST, the US National Institute of Standards and Technology, has finally published a trio of new standards for post-quantum cryptography (PQC) in an attempt to get ahead of the coming cryptography crisis that’s forecast for the time when quantum computers get powerful enough to crack current RSA (Rivest-Shamir-Adleman) public-key encryption standards. Although the RSA algorithm was published in 1977 and predates the Internet by a decade or so, today’s Internet services, including the Secure Shell (SSH), OpenPGP, S/MIME, and SSL/TLS protocols, rely on RSA for encryption and digital signature functions. Other public-key crypto standards, … Read More → "NIST Issues New Quantum Crypto Standards for Cyberspace"

New PSoC Brains for Motor and Power Applications

by Max Maxfield

October 10, 2024

I’ve often been moved to say that I don’t have many regrets in my life. I even used to believe this myself, right up until I read The Midnight Library by Matt Haig. Now I’m discovering regrets I never even knew I had. Although this may not appear to be a ringing endorsement, I’m actually a huge fan of this book. The fact that it has a 4.3 out of 5-stars with over a quarter of a … Read More → "New PSoC Brains for Motor and Power Applications"

Unobtainium is where you find it: What happens when you can’t source an old IC?

by Steven Leibson

October 9, 2024

If you’ve designed electronic systems for a while, or if you’ve repaired vintage electronic equipment, no doubt you’ve run into the fascinating term “unobtainium.” Here’s Wikipedia’s definition of the term:

“Unobtainium originally referred to materials that do not exist at all, but can also be used to describe real materials that are unavailable due to extreme rarity or cost.”

Wikipedia lists a few examples, including parts for old cars made before the 1960s, parts for reel-to-reel tape recorders, and rare vacuum tubes that haven’ … Read More → "Unobtainium is where you find it: What happens when you can’t source an old IC?"

Adiuvo Engineering’s Leonidas Spartan 7 Tile makes it easy for you to drop an FPGA into your design

by Steven Leibson

October 7, 2024

By the time you read this article, you should be able to get Adiuvo Engineering’s new Leonidas Spartan 7 Tile. It went on sale for pre-order in August for £150.00. Unlike FPGA development boards, Adiuvo’s Leonidas Spartan 7 Tile is designed to be used as a component in a larger design. The 59x59mm tile is a circuit board with a periphery of castellated interconnect pads that will take 0.1-inch headers or will just solder down onto a larger PCB without the headers.

Have You Forgotten Anything?

by Max Maxfield

October 3, 2024

I just had an interesting video conference call. It started off as so many things do… with people laughing at me (I live for the day when people laugh *with* me rather than *at* me). First, there was the fact that my name invariably comes up as “Max the Magnificent” in conference applications like Zoom and Teams. I can no longer recall how this came to be, and I have no idea how to change it, so there we are.

On the other hand, now I come to think about it, why … Read More → "Have You Forgotten Anything?"

Jim Handy, The Memory Guy, steps in with a report on CXL’s near-term future

by Steven Leibson

October 2, 2024

Back in May, I discussed CXL and gave some reasons that I thought would lead to its success. (See “The Adventures of CXL Across the 3rd Dimension.”) In that article, I mentioned that my friend Jim Handy, “The Memory Guy,” was writing a report about CXL and applying his own analysis skills to the topic. Well, the report is finally finished. It’s titled “CXL Looks for the Perfect Home,” and Handy has a lot to say about CXL in the report’s 60 … Read More → "Jim Handy, The Memory Guy, steps in with a report on CXL’s near-term future"

Eeek! GenAI-Powered Design and Verification EDA Tools

by Max Maxfield

October 1, 2024

I just got off a video conference call with a company I cannot name that’s developed a technology I cannot discuss to power a product I am forbidden to talk about at this time. But I fear I’ve said too much. Suffice it to say that this product is going to enable a new generation of high-performance computing (HPC) and artificial intelligence (AI) platforms in data centers.

But that’s not what I wanted to talk about, so I’ll say no more.

Of course, saying “I’ … Read More → "Eeek! GenAI-Powered Design and Verification EDA Tools"
