Researchers use Claude Opus 4.8 to auto-design sub-THz transmitter with EDA tools
Researchers at an unnamed lab introduced TACS-RF, a framework where a Claude Opus 4.8 LLM agent automates RF and mmWave module design by directly controlling industry-standard tools like Cadence Virtuoso/Spectre and Ansys HFSS. The agent designed a 240–251 GHz sub-THz transmitter in a 90 nm SiGe BiCMOS process, including a 60 GHz push-push Colpitts VCO, power drivers, a frequency doubler, and a…
Key points
- Claude Opus 4.8 LLM agent designed a **240–251 GHz sub-THz transmitter** using EDA tools like Cadence Virtuoso/Spectre and Ansys HFSS
- Final design delivered **+5.1 to +6.3 dBm** output power and **-80 to -88 dBc/Hz** phase noise at 1 MHz offset
- Researchers call it a **‘text-to-ASIC’** prototype, but it’s not yet a commercial product or tool
The paper describes a semi-autonomous workflow where the agent handles sub-block synthesis and matching networks while humans oversee parasitic extraction and EM verification. The authors frame this as a step toward ‘text-to-ASIC’ hardware design, though the work remains experimental and not yet deployed in industry tools.
