I wrote for Circuit Cellar in a column titled “Programmable Logic in Practice” from 2013-2015. This column detailed various work around FPGAs. The column later became my “Embedded System Essentials” column, which primarily dealt with security issues in…

I’ve got a SASEBO-W board, which has a FPGA & a FT2232H for high-speed USB comms. I was seeing errors on the high-speed USB device, and couldn’t figure out why: Power Split The SASEBO-W is a multi-purpose board including a Xilinx LX150 Spartan 6 FPGA and a…

I’ve been working with Xilinx’s new High Level Synthesis tools built into Vivado. I’m slowly working on posting some more complete tutorials. In the mean-time here is a simple tutorial about making a Finite Impulse Response Filter on a real ADC/DAC board…

Here is an ongoing project: it’s a high-speed ADC combined with some nice input preprocessing (amplifier). It’s all controlled by a FPGA on the Avnet LX9 Microboard, so it just plugs into that. Here is a simple python app (still being improved) to control it:…

I was recently working on a project which needed more gates than I had in my trusty current FPGA Board (Spartan3-200 on DLP-FPGA-HS). I quickly found the Avnet Spartan 6 LX9 board (AES-S6MB-LX9-G), which I could buy for $90 and have here in a few days. It…
