First Steps with the Tang Nano FPGA Development Board

The Tang Nano is a very very low cost FPGA development board by Sipeed featuring a GW1N-1-LV FPGA produced by GOWIN Semiconductors. GOWIN is another Chinese chip manufacturer entering the FPGA arena, like Efinix and Anlogic.
The GW1N-1-LV is the smallest member of GOWINs “Little Bee” series, which consists of small footprint instant-on FPGA devices for IoT and interfacing solutions.

Gigabit Transceiver(s) for a Cheap FPGA Development Board

There are a lot of FPGA development boards out there to buy. Official vendor boards with the latest advanced devices on it can easily cost several thousand Euros.
Hobbyists and makers are more interested in FPGA development boards within an affordable price range (roughly << 100 $/€). The logic resources and feature set of the FPGA devices on these boards is not that important on the other hand. The main application for makers/hobbyists is small projects and self-learning, I assume, and not rolling out their own 5G equipment.

First Steps with the iCEBreaker FPGA Development Board

The iCEBreaker board is the first FPGA development board with a fully open-source toolchain, which allows to go all the way from HDL code to configuration bitstream. All the schematics and hardware information is openly available at no extra cost.

VLSI tools in 500 LOC or Longing for Attention

My VLSI tools take a chip from conception through testing. Perhaps 500 lines of source code. Cadence, Mentor Graphics do the same, more or less. With how much source/object code?

– Chuck Moore, the inventor of Forth –

Now, I’ve seen chip design tools by the likes of Cadence and Mentor Graphics. Astronomically costly licenses. Geological run times. And nobody quite knows what they do.
