This article evaluates the proficiency of 11 contemporary Large Language Models (LLMs) in performing electronic circuit analysis.

Some days ago I ordered a testing PCB from PCBWAY, and today the package has arrived!

In hardware design, tedious manual data entry is a common bottleneck.

AGILA will be a new open-source board with the Altera Agilex 3 FPGA, 2 GB to 8 GB of LPDDR4 RAM and the PCI-Express interface.

The picture below is an extract from Power-Supply Block Diagram of the official Agilex 3 Devkit.

Theoretically, Agilex 3 FPGA does not require any external clock signals to load bitstream and to operate an (asynchronous) user design.

**What the local company manager expects: ** 1.

Agilex 3 FPGA supports loading of the configuration bitstream by multiple methods.

Agilex 3 FPGA supports PCI-Express via its four GTS transceiver links.

Presently (2025) there are two perspective busses for connecting DRAM devices in embedded systems: DDR3L LPDDR4 (and its lower-power variant LPDDR4X) The DDR3L supports traditional DDR multidrop bus topology with VTT termination and multiple memory devices

Ever since I attended the Altera FPGA workshMicronop featuring their new Agilex 3 device, I am thinking if Agilex could be the right FPGA to implement a general-purpose computation accelerator (i.e. a GPU) with a fast PCI-Express interface and a significa…

Recently I attended Arrow’s Agilex 3 FPGA workshop, which promoted, obviously, the new Altera Agilex 3 FPGAs.

There is an ongoing Indiegogo campaign called “X65GS 65816 Gaming Console”, see screenshot below.

I started a new debugger tool for my x65 project.

I designed an enclosure box for the x65-SBC computer.

As mentioned in previous post, Matej asked me if Dreamtracker app is running on X65.

It’s Autumn again and I am revisiting my Project X65.

In the previous post I have mentioned that I am working on a port of the 32-bit Forth interpreter OF816 to my X65-SBC, an 8/16-bit retro computer that I am building.

I am working on a port of the 32-bit FORTH interpreter OF816 for my X65-SBC computer with the 65C816 CPU.

Symptoms: Running Fedora 38 and 39 with kernels 6.7.7 on AMD Ryzen 5 with AMD GPU RX570 (Sapphire Radeon PULSE ITX RX 570 4GD5, 4GB GDDR5) sometimes results in a blank screen (no video signal, monitor going to sleep mode) after the boot.

Modern microcontrollers and microprocessors have built-in facilities for external debuggers to read/write registers, set breakpoints and generally fully control the CPU.

In the last 2 months I have re-done my X65 double-decker computer into a Single Board Computer (SBC).

In X65 the assembled CPU is either the 8-bit W65C02S or 16-bit W65C816S.

This document discusses the FM sound synthesis in the Commander X16 and in my x65 computer.

X65 is a retro/modern 16-bit computer that I designed inspired by the architecture of Commander X16 (CX16).

SNES Controllers typically look like this: SNES controller is a cheap and easy way how to add a joystick interface to a DIY project.

The Open-X65 GIT repository is now public: https://github.com/jsyk/x65 Note: this is not a release!

My Open-X65 project achieved a milestone: the unmodified X16 ROM can be loaded and runs!

Since the first post a lot of happened: Motherboard PCB (bottom) has arrived, it is now part-way assembled with components and working quite well.

I am starting a new hobby project called X65: I intend to create an open-source computer based on the “vintage” 6502 processor, which is still in production as the W65C02.

Mywayback is a complete rewrite of my previous timeback archival tool.

Engineers’ Tribute is an endless well of electronic technology sites, perfectly suited for studying during long winter evenings (or lockdowns.. :-) ) Checkout this handy wire-gauge chart made by PEI-Genesis.

Go see my Vacuum Tube watch “EVERGLOW” V2.1

The “EVERGLOW” Watch is a vacuum tube clock put on the wrist: Features: Soviet VFD tube IVL2-7/5 Time (24h), Date, (dd-mm-yyyy), day of week (Mo-Tu-We-etc).

The Vacuum Tube Watch project is now released in version V2.1 “EVERGLOW”.

UPDI - Unified Program and Debug Interface - is the new programming and debugging interface on new ATtiny MCUs from Microchip.

I created a smal 100x100mm PCB mini-panel of some of the SMT breakout boards from Adafruit.

Here you can find documentation about my DIY Analog Curve Tracer.

A signature curve tracer is a simple yet useful device in any electronics lab.

New AVR processors from Microchip/Atmel use a 1-wire UPDI interface for flash programming.

NXP’s PN7120 is NFC controller for contactless communication at 13.56MHz.

Once upon a time, I decided it is a good time to upgrade the version of gcc compiler we use in our ARM926-based firmware project.

The X86 has always supported unaligned accesses.

This is Part 2 of a two-part series on Ethernet RMII.

This is Part 1 of the two-part series on Ethernet RMII.

[half-way through; click a pic to see hi-res] [connections to bga] [finished “product”] And it (almost) worked!

During pre-Christmas sale on Seeed Studio Bazaar they offered these digital radio modules with the nRF24L01+ chip for only US$0.81 each.

This issue bugged me a long time, finally I solved it this evening.
