Создаем I2C Master Controller на Verilog. Тестируем ядро

По результатам написания прошлой статьи у нас получился объемный модуль для реализации функций низкоуровневого управления шиной I2C, который формирует управление линиями SCL/SDA, поддерживает мониторинг шины, ведет передачу и прием данных. В этой статье я предлагаю организовать полноценное вдумчивое тестирование всего что получилось. Всем заинтересованным - добро пожаловать под кат! 🙂

Some more workshop work on the SDG2042X Linux GUI today (got a free Monday): Fixed 5 bugs in this round, including ARB handling on the real instrument, sweep fallback timing, preset handling, and one unsafe input-parsing corner.

I hope GUI is getting a bit less fragile / more reliable.

Project 0003: SDG2042X GUI v0.2.* — first patch round and bug tracker setup – togo-lab.io

Today I worked on my remote control GUI for the SDG2042X.

This project is now becoming usable for my test bench: Did some bugfixes, added configuration file, path settings (screenshot and pre-saved Settings) and, most important, context-sensitive input fields that depend on the waveform.

But the GUI still in a very early stage, at example, the ARB management isn't really working yet, that's still on my to-do list.

& yes, the GUI is ugly as hell, but at this stage of the project, the functionality is more important to me.

Improving my test bench for future projects, I wrote a small PyQt5 GUI to control my Siglent SDG2042X from a remote Ubuntu desktop.

It handles basic waveform setup, sweeps, bursts, presets (so you can adjust at the generator and than load down for later), ARB upload/download (not fully tested yet), and SCPI commands, also screenshots.

I’m more of a hardware guy than a coder (for sure there will be some bugs), so feedback are welcome. Fork if you like.

A literal DIY open bench
I am not sure if I'd buy it again, but it will serve its purpose

Would a 25Mhz oscilloscope be enough for testing on modern computers up to say the XPish era? #RetroComputing #TestBench

Yesterday we got the #VHDL #testbench for part of our #opensource #DVB-S2 #fpga amateur #satellite encoder working (and it PASSED!) on the command line, using GHDL. This is great! 🌈

The parallel effort in Xilinx Vivado didn't work, because vunit (a necessary component of the testbench) doesn't support xsim in Vivado.

This word salad boils down to "open source helps advanced digital communications in amateur radio"

The support for vunit working in Vivado has been a filed issue since 2017.
