Felipe Sens Bonetto used AI agents to write openTPU, an LLM inference accelerator with its own instruction set, simulator, compiler and host software. On an Inspur PCIe card with a Xilinx Kintex-7 and 2 DDR3 channels it runs 10 models, including Qwen3 and Gemma 4, with their real weights. A README GIF shows the chat demo running on the card.

Munetomo Maruyama had Claude Code design mmRISC-2, a 64-bit RV64GC RISC-V core, and brought it up on a Digilent Arty A7-100T. Claude wrote the specification, SystemVerilog RTL, testbenches and documents; Maruyama ran Vivado and the board. Bring-up logs in the repository record Linux 7.2 booting to a shell at 50 MHz and a 120-minute stress test passing.

In an Octopart video, one prompt sends Claude Code through a digital low-pass filter on a Digilent Cmod S7 FPGA board. It writes and simulates the filter, then programs the board over JTAG. Through MCP servers for an Analog Discovery 2 and a Rigol scope, it sweeps test tones at 1, 5 and 15 kHz against the 10 kHz cutoff.

Craig Hollabaugh had Claude Code boot Linux overnight on an Icepi Zero, a Lattice ECP5 FPGA board with no hard CPU. The agent installed LiteX and built a VexRiscv soft core that boots OpenSBI, Linux 5.14 and BusyBox to a root shell over USB serial. The 10-minute video logs into the running system on the board.

Dimdim had Gemini 3.1 Pro write the Verilog for an audio reclocker on a MAX 10 10M08 board. He pasted code from the chat into Quartus. The design passes I2S through a dual-clock FIFO, adds DSD and S/PDIF input and buffers in PSRAM. Gemini, Claude Sonnet 4.6 and Claude Opus 4.7 all failed to make a PRBS-15 test work.
