Getting Started with the Forgix Board: Efinix Trion T8 + RP2354

A few weeks ago, Adiuvo Engineering and Training released the Forgix board, a (very) small Teensy 4.0 form-factor board that pairs an Efinix Trion T8 FPGA with a Raspberry Pi RP2354. It is not the first board that features the great combo of a small FPGA and an RPxx, actually in this blog I show ...

Using the Red Pitaya STEMlab 125-14 PRO Gen 2 as an SDR in GNU Radio

The red Pitaya STEMlab 125-14 PRO Gen 2 slogan was “The swiss army knife for engineers”, and it is very true. The board is a compact Zynq-based system with two analog inputs and two analog outputs, and it can be used as a signal generator, an oscilloscope, a spectrum analyzer, a logic analyzer, a...

Implementing a Single-Precision Floating-Point Biquad on Versal

In my daily work, y I often need to implement digital filters on FPGAs, and since I usually work with 7 Series FPGA, all my filters are designed using fixed-point arithmetic. Is true that I can implement floating-point arithmetic using those FPGAs, but it would be an overkill in terms of resource...

CryptoliteICE: an Open-Source FPGA-Based TRNG

One of the missions of an engineer, is selects the device that fits better for a project. In the case of FPGA engineers, of even any embedded software engineer, many times we tend to use always the same devices because we feel comfortable with them, we have experience with them, the toolchain con...

Building PetaLinux for a Versal-Based Board

This week I have been busy working on my talk in the next FPGA Developer’s Forum, which will be focused on the AMD Versal architecture and the iWave Global iG-G57D. As part of the preparation, I needed to build a PetaLinux image for the board, which is a common task for anyone working with embedd...

Exploring Versal ACAP with the iG-G57D Board

I have been using Zynq7000 and Zynq MPSOC devices for years, but I had not had the chance to work with AMD’s latest adaptive platform, Versal ACAP, until now. A few weeks ago, the iWave Global iG-G57D board, based on the Versal AI Edge VE2302, landed into my desk thanks to iWave Global.

Getting started with Agilex 3 and floating-point DSP operations

I have been working with Xilinx (now AMD) FPGAs for years, so when the Agilex 3 FPGA and SoC C-Series Development Kit landed on my desk I knew the transition would involve some hard changes. I used Quartus in my University days with a Terasic kit based on a Cyclone II (DE2) and later a Cyclone IV...

Application Notes

[AN001] Designing from zero an IIR filter in Verilog using biquad structure and bilinear discretization.

Filtering is likely the most common DSP algorithm that any embedded engineer has to design, no matter it they are developing for an STM32, or TI DSP or, of course, en FPGA. Filtering is such important because the majority of the applications are connected to the real world, so they need to captur...

[AN002] Running subcycle average models on Speedgoat Performance System.

Materials like Silicon Carbide (SiC) or Gallium Nitride (GaN) are making our power electronics converters faster and faster. This means small inductors and capacitors that make, in most cases, the cost of the devices decrease. This also means that the control devices also have to be faster, and n...
