Nowadays you can find many low-cost microcontroller devboards (starting from just few dollars/euros). More recently, we’ve seen ARM Cortex kits for $10-$50, the flowering of the whole Arduino ecosystem, and of course, the Raspberry Pi. It’s microcontroller heaven with very many dev boards available. You you want more performance, there is a wide selection of Linux friendly single board computers in around $35 to $200 range.
What do you want to try next after microcontroller dev boards? Maybe FPGA. A field-programmable gate array (FPGA) is an integrated circuit designed to be configured by a customer or a designer after manufacturing. FPGAs contain programmable logic components called “logic blocks”, and a hierarchy of reconfigurable interconnects that allow the blocks to be “wired together” – somewhat like many (changeable) logic gates that can be inter-wired in (many) different configurations. Logic blocks can be configured to perform complex combinational functions, or merely simple logic gates like AND and XOR.
Those of us wanting a cheap “in” to the FPGA world have been less lucky than developers looking for microcontroller dev boards. FPGA boards under $100: Introduction article is indicting that the times, they are a changin’. Many FPGA devkits, from both chipmakers and third parties, have broken – or downright shattered – the $100 barrier, opening the door to low-cost FPGA prototyping, education, hobby projects, and so on. FPGA boards under $100: Introduction article offers a good overview of what is available.
Here are some interesting additions to the listed boards:
Hacklet 28 – Programmable Logic Hacks posting tells about Arduino-Compatible FPGA Shield. The shield features a Xilinx Spartan 6 FPGA and is available in The Hackaday Store. It has the needed regulators and level shifters. The price is $69.97. Not sure where to start? Check out Spartan-6 FPGA Hello World! that uses Xilinx’s free tool chain to getting a “hello world” led blinker running!
Hacklet 28 – Programmable Logic Hacks posting also mentions Chameleon. Chameleon is an Arduino compatible FPGA board with a Xilinx Spartan 3A FPGA on-board. The Chameleon Arduino-compatible shield board was designed to support two general application areas: (1) soft-core processors, and (2) intelligent serial communications interface.
Cheap FPGA-based HDMI Experimenting Board project is designing a (relatively) cheap little board for experimenting with HDMI using a Spartan-6 FPGA.

Java On GPUs And FPGAs
https://hackaday.com/2020/03/11/java-on-gpus-and-fpgas/
There was a time when running a program on an array of processors meant that you worked in some high-powered lab somewhere. Now your computer probably has plenty of processors hiding in its GPU and if you have an FPGA, you have everything you need to make something custom. The idea behind TornadoVM is to modify OpenJDK and GraalVM to support running some Java code on parallel architectures supported by OpenCL. The system can utilize multi-core CPUs, GPUs (NVIDIA and AMD), Intel integrated GPUs, and Intel FPGAs.

NEO430 Puts A Custom MSP430 Core In Your FPGA
https://hackaday.com/2020/04/27/neo430-puts-a-custom-msp430-core-in-your-fpga/
We are certainly spoiled by all the microcontroller options nowadays — which is a great problem to have. But between the good old 8-bit controllers and an increasing number of 32-bit varieties, it almost seems as if the 16-bit ones are slowly falling into oblivion. [stnolting] particularly saw an issue with the lack of 16-bit open source soft cores, and as a result created the NEO430, an MSP430 compatible soft processor written in VHDL that adds a custom microcontroller to your next FPGA project.
However, what impresses most is all the work and care [stnolting] put into everything beyond the core implementation. From the C library and the collection of examples for each of the controller’s features, so you can get started out of the box with GCC’s MSP430 port, to writing a full-blown data sheet, and even setting up continuous integration for the entire repository.

The DOOM Chip

It’s a trope among thriller writers; the three-word apocalyptic title. An innocuous item with the power to release unimaginable disaster, which of course our plucky hero must secure to save the day. Happily [Sylvain Lefebvre]’s DOOM chip will not cause the world to end, but it does present a vision of a very 1990s apocalypse. It’s a hardware-only implementation of the first level from id Software’s iconic 1993 first-person-shooter, DOOM. As he puts it: “Algorithm is burned into wires, LUTs and flip-flops on an #FPGA: no CPU, no opcodes, no instruction counter. Running on Altera CycloneV + SDRAM”. It’s the game, or at least the E1M1 map from it sans monsters, solely in silicon. In a very on-theme touch, the rendering engine has 666 lines of code, and the level data is transcribed from the original into hardware tables by a LUA script. It doesn’t appear to be in his GitHub account so far, but we live in hope that one day he’ll put it up.

An Open Source HDMI Implementation For FPGAs
https://hackaday.com/2020/06/02/an-open-source-hdmi-implementation-for-fpgas/
With some clever hacks and fast IO work, it’s possible to get your average garden-variety microcontroller to output some form of video. Old analog standards like composite and VGA are just slow enough that it’s possible to bitbash one’s way to success. If you’re serious about video work, however, you’ll want something more capable. For those use cases, [purisame]’s got what you need – an open source HDMI implementation for FPGAs.
Unlike other free and open source projects in this space, [purisame] has eschewed simply outputting compatible DVI signals on the port. This implementation is pure HDMI 1.4b, enabling the extended capabilities this brings, like combined video and audio streams. Thus far, it’s been tested on Xilinx and Altera platforms, though it may be compatible with Lattice, too.

Open Source HDMI for FPGA
https://www.hackster.io/news/open-source-hdmi-for-fpga-f3e885b41aa5
Add an open source, true HDMI port to your FPGAs with this HDL implementation of an HDMI controller.
While the major FPGA vendors such as Xilinx and Intel provide IP blocks for an FPGA developers to implement HMDI signaling in their designs, this locks the design to that particular FPGA chip family. When the event arises such that a design needs to be portable between FPGAs from various vendors, developers turn to either an open source implementation of HDMI or to writing their own from scratch.
Written in System Verilog, this pure HDMI 1.4b implementation can be tailored to fit any system specifics that it is instantiated within. From double data rate I/O to the specific desired refresh rate, the top level System Verilog file can control how the module is built in the programmable logic of a given FPGA.
One thing to keep in mind with this, and any HDMI implementation on FPGA, is that FPGAs do not support the TMDS (transition-minimized differential signaling) communication interface. Thus LVDS with 100nF capacitors in series on the lines to try to mimic the impedance that the twisted pair lines of TMDS has may be necessary.

GCC for FPGA: SymbiFlow Open Source Toolchain
https://www.hackster.io/news/gcc-for-fpga-symbiflow-open-source-toolchain-254cf1ab15ff
SymbiFlow is an open source toolchain with the goal to become the GCC compiler of FPGA toolchains.
SymbiFlow is an end-to-end FPGA synthesis toolchain with the goal to provide a fully open source, multi-platform, and vendor-neutral design tool option for FPGA developers. It contains all of the necessary tools to convert a Verilog design to a final bitstream, and is simple to use despite the face that the whole synthesis and implementation process is not a trivial one.
In the two main steps in FPGA development (synthesis and implementation), synthesis is responsible for taking the logic of the HDL written by a developer and converting it into the equivalent digital logic gate configuration. This is followed by implementation where this digital logic gate configuration is physically placed and routed in the target FPGA chip.
Since the place and routing of the design is fully dependent on the specific silicon layout design of a given FPGA chip and vendors keep this proprietary, this is where an FPGA developer gets locked into a specific toolchain.
SymbiFlow uses the open source synthesis tool, Yosis. The synthesized design is output to nextpnr to map the design to the logic gates within the FPGA using rules and parameters for the target FPGA chip as specified by SymbiFlow. These rules and parameters have been developed from their reverse engineering of bitstreams for various FPGA chips.

UART with automatic baud rate determination
SPI or I2C
Read and write common EEPROMs and flash chips
Read and write common EPROMs including a data rescue function
Program AVR chips via SPI
Play back JTAG SVF files
Debug ARC and some MIPS CPUs
Program XC9500LX CPLDs
Communicate to several wireless radios and CPUs
Do sound synthesis

The revC board is the first to be relatively functional and sports 16 I/O pins operating at up to 100 MHz, although the documentation hints that 6 MHz might be the top of what’s easily accomplished.

The Raspberry Pi form factor FPGA, the Zynqberry, just got a little cousin with the announcement of the ZynqberryZero!
The ZynqberryZero mirrors the Raspberry Pi Zero with 512 MByte DDR3L SDRAM, 40 pin HAT header, 26 total GPIO, two micro USB ports, mini HDMI connector (type C), CSI-2 connector (camera), and micro SD card slot. However, it packs its processing power punch with the Xilinx Zynq-7000 system on a chip FPGA with 16 MByte flash memory available for programming.
This Zynq-7000 FPGA hosts a dual Arm Cortex-A9 MPCore with CoreSight at a speed of 667MHz that is physically instantiated in the middle of the programmable logic of the FPGA, thus making it a full system on a chip (SoC). This is in contrast to the Pi Zero’s single-core 1GHz Arm BCM2835. The extra flexibility of the programmable logic surrounding the Arm processor in the Zynq chip makes the design options for the ZynqberryZero almost infinite.

For most people, adding WiFi to a project means grabbing something like an ESP8266 or an ESP32. But if you are developing your own design on an FPGA, that means adding another package. If you are targeting Linux, the OpenWifi project has a good start at providing WiFi in Verilog. There are examples for many development boards and advice for porting to your own target on GitHub.
The demo uses a Xilinx Zynq, so the Linux backend runs on the Arm processor that is on the same chip as the FPGA doing the software-defined radio. We’ll warn you that this project is not for the faint of heart. If you want to understand the code, you’ll have to dig into a lot of WiFi trivia.
