BML FPGA Design Tutorial Part-16ofN : Test Benches
2024.09.29 : I’m BSEE Kevin Hubbard from Seattle, WA. I design digital logic circuits. My journey started more than 40 years ago designing digital circuit boards. My first was a simple 5V TTL logic plug-in expansion board for my 8-bit Apple ][+ computer as a teenager in the 1980’s. In the 1990’s I eventually transitioned ( and got paid! ) to design chips – PALs, CPLDs, early sub-micron (350nm) FPGAs and eventually digital ASICs (250nm, 180nm ) during the LSI Logic heyday years of late 1990’s to early 2000’s.
I have circled back to FPGAs these days, but now deep sub-micron...

Reverse-engineering a three-axis attitude indicator from the F-4 fighter plane
https://invidious.privacyredirect.com/watch?v=uKzj5shVtlo
We recently received an attitude indicator for the F-4 fighter plane, an instrument that uses a rotating ball to show the aircraft's orientation and direction. In a normal aircraft, the artificial horizon shows the orientation in two axes (pitch and roll), but the F-4 indicator uses a rotating ball to show the orientation in three axes, adding azimuth (yaw).1 It wasn't obvious to me how the ball could rotate in three axes: how could it turn in every direction and still remain attached to the instrument?
The attitude indicator. The "W" forms a stylized aircraft. In this case, it indicates that the aircraft is climbing slightly....Inside a ferroelectric RAM chip
Ferroelectric memory (FRAM) is an interesting storage technique that stores bits in a special "ferroelectric" material. Ferroelectric memory is nonvolatile like flash memory, able to hold its data for decades. But, unlike flash, ferroelectric memory can write data rapidly. Moreover, FRAM is much more durable than flash and can be be written trillions of times. With these advantages, you might wonder why FRAM isn't more popular. The problem is that FRAM is much more expensive than flash, so it is only used in niche applications.
