Understanding the PID regulator.

I always remember when the Optimization and Optimum Control teacher at the university told us that 90% of the regulators we will find in our life, will be PID, 5% will be LQR and the other 5% will be other complex regulators. PID control has become the most used control because of its simplicity ...

Modeling a Boost converter in Speedgoat Performance.

It has been some since the last time we talked about Speedgoat, and during this summer I have been working with it deploying some models. In this blog we saw how to deploy a Buck converter electrical model using Speedgoat, this time we are going to deploy another converter model a Boost converter...

Deploying a converter model on the Leonidas board

When discussing real-time simulations, we often think of big and powerful devices. In the same way, when we talk about Hardware-In-the-Loop (HIL), we think on FPGA like the Kintex7 used in the Speedgoat Performance so, do we need huge FPGAs to perform real-time hardware simulations? The short ans...

Co-simulating Verilog and SPICE circuits with QSPICE

If you are an engineer in any field related to electricity, in your degree I am pretty sure that you have simulated many electronic circuits, from linear circuits based on operational amplifiers to power circuits like switched-mode power supplies or DC/AC converters. Simulation is a crucial step ...

Building Linux with Buildroot for the KD240 Kit

If I say Linux and Zynq MPSOC, I am pretty sure that most of you think of Petalinux. Petalinux is the official AMD’s tool that eases the build of a Linux distribution for FPGA and SoCs. What Petalinux gives us is a set of pre-configurations or recipes for Yocto, which is the tool running behind P...

Creating a HDL Coder Support Package for Leonidas board

When we are working in any engineering field, probes of concept are essential in order to check if an idea can become a real product. The time spent in the probe of concept is crucial either to accept that probe of concept as a future product or to discard the idea finally. Unfortunately, FPGA an...

The Gate Array News 2024.

Another season comes to an end, and The Gate Array News is here. This is the second edition of this series os articles, and I think that it would be a very interesting exercise to recover the news of the last TGA News. In 2023 we talked about the announcement of Spartan 7 Ultrascale+. I thought ...

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...
