BrisbaneSilicon ELM11-Feather is a “microcontroller” board based on a Gowin GW1NR FPGA that is natively programmable in Lua, C, SystemVerilog, and VHDL. Compatible with the Adafruit Feather form factor, the board features GPIO headers, a built-in debugger, a USB-C port for power and programming, and a 2-pin header for a LiPo battery. The company calls it a microcontroller board because the FPGA runs a PicoRV32 MCU softcore at up to 75 MHz with 1MB RAM and 8MB flash, programmable with Lua, and the user can also customize hardware layers with RTL code using the remaining FPGA fabric.

Dabao board features open-source hardware Baochip-1x RISC-V MCU (Crowdfunding)
An open-source hardware board usually features a closed-source microcontroller or processors, but the Dabao evaluation board goes further with the open-source Boachip-1x MCU, whose RTL files are available. It’s also manufactured in such a way that it is inspectable with the Infra-Red, In Situ (IRIS) technique, so users can look at the silicon and confirm they’ve got the right chip in a non-destructive way. Baochip-1x is a “general-purpose” microcontroller with a 350 MHz Vexriscv RV32-IMAC CPU core, a BIO accelerator for I/Os with four 700MHz PicoRV RV32-EMC CPU cores, 4MB of ReRAM, 2MB SRAM, a USB interface, various other I/Os, and hardware secure elements such as cryptography accelerators, key stores, one-way counters, true random number generation, and hardware attack countermeasures such as glitch sensors and a security mesh. The Dabao board itself is pretty basic with the microcontroller, two 16-pin headers for I/Os, a USB-C port for power and programming, […]
$4 Shrike-lite FPGA board combines 1120 LUTs Renesas ForgeFPGA with Raspberry Pi RP2040 MCU
Shrike-lite is an ultra-cheap FPGA board based on a 1120 LUTs Renesas ForgeFPGA device (SLG47910V) and also equipped with a Raspberry Pi RP2040 microcontroller. The board also features a USB-C port for power and programming, two 18-pin headers and a 12-pin PMOD-compatible header for I/Os, as well as Boot and Reset buttons, but not much else since it’s designed as a minimal development board.

GateMate Integrated Logic Analyzer (ILA) deep dive
CNXSoft: This is a guest article by Dave Fohrn, Embedded Software Engineer at Cologne Chip AG, that goes into detail about the company’s open-source integrated logic analyzer (ILA) for GateMate FPGA chips. A field-programmable gate array (FPGA) is a highly flexible integrated circuit in which complex logic circuits can be configured. They are often used as custom computing units in digital circuits because of their ability to process data quickly and in parallel using individually configured circuits. The digital circuits designed specifically for FPGAs are usually developed in a hardware description language such as Verilog or VHDL and are known as gateware. The term “gate” refers to the configurable digital logic units in the FPGA on which the individual gate circuits are implemented. An effective design can accelerate the computing process by strategically utilizing the various resources available in the FPGA, processing data in parallel, and intelligent implementing pipelining. A […]
Cologne Chip releases an open-source integrated logic analyser (ILA) for GateMate FPGA chips
Cologne Chip’s “Integrated logic analyzer” (ILA) project is an open-source Verilog implementation of a logic analyzer running on the company’s GameMate A1 FPGA and designed to capture internal signals. When we first covered the GameMate A1 FPGA we noted Cologne relies on the open-source Yosys framework coupled with a proprietary, but free-of-charge, place & route tool contrary to most other FPGA vendors that only offer closed-source proprietary development tools. The German company has now released the GateMate integrated logic analyzer project to help customers debug their FPGA designs. The project includes the digital circuit of the ILA designed in the hardware description language Verilog and a Python program (ILA Control Program) used to configure the configuration of the ILA from the design under test (DUT) and provide an interface with the user during the debugging process. The user will also need a GateMate FPGA toolchain and GTKWave open-source program to […]
