Teaching AI to Semiconductor Students, Engineers, and Fabs

My mission today is to inform you about a university course that is no longer offered and a master’s degree program that is not yet available. Intrigued? Read on…

To set the scene, first let me remind you that I originally hail from England. I started at Sheffield Polytechnic (now Sheffield Hallam University) in the summer of 1975. You can read more about … Read More → "Teaching AI to Semiconductor Students, Engineers, and Fabs"

You May Scoff, But AI-Powered PCB Layout Is Really Real

Recently, I re-watched the epic science fiction movie, 2001: A Space Odyssey. Although this film was released in 1968, I don’t think I saw it on the big screen until 1969, when I was 12 years old. I know that by the time I watched the film, I’d already read the book, for which I was very grateful, because that’s pretty much key to understanding what’s going on in the first part of the film. … Read More → "You May Scoff, But AI-Powered PCB Layout Is Really Real"

Next-Generation Motion Sensing Facilitates Immersive Spatial Audio

I was sitting here thinking (don’t worry, I’ll try not to make a habit of it). I was contemplating how, even when we think things have evolved to be rather good (technologically speaking), someone invariably leaps onto the center of the stage with a fanfare of flugelhorns, brandishing a “new and improved” solution.

This just happened to me … Read More → "Next-Generation Motion Sensing Facilitates Immersive Spatial Audio"

Hi Peter -- on the one hand, I wish the film had been a bit closer to the book at the end -- on the other hand, both were different interpretations that stood proud in their own right. Now I want to watch the film and read the book AGAIN!

Hi Max, Thanks for a really interesting article. Point well made - how many times have I started on a design only to have to back out after realising that I was heading down towards a non-routeable dead-end? (Answer - many!) Being able to "explore the solution space" before making ...

I, too, read the book of 2001 A Space Odyssey before seeing the movie in a theater. I remember tiny details in the future part of the movie giving a sense of large structures: office workers seen through windows of the rotating space station. In the book, Dave's pod lands atop ...

If you read part 1 of this article, etssp, you'll see that the original device used to design the block 1 computers was a Type G IC containing one nor gate. Die microphotographs of this device do indeed look like they have a very different logic gate layout. Fairchild had not developed ...

Note that the Apollo dual 3-input NOR gate is not the same as the 9915! The Apollo chip has the outputs of the NOR gates at pins 1 and 9 [1], while the 9915 has outputs at pins 4 and 9 [2]. This results in two completely different layouts of the IC, as can be seen in the ...
