An Open-Source Standard-Cell Library for IHP 130 nm Developed by Students

arXiv:2609.29965v1 [cs.AR] 24 Sep 2026

1. Department of Information Technology and Electrical Engineering, ETH Zurich, Switzerland

* The open-source EZ130 8T standard-cell library is available at https://ez.ethz.ch

Abstract: Standard-cell libraries form the critical interface between transistor-level circuit design and automated digital design flows, yet their design and characterization are rarely covered in depth in digital VLSI courses. This paper presents VLSI 5, a graduate-level course at ETH Zurich in which students design, lay out, characterize, and integrate their own standard cells using IHP’s open-source 130 nm SG13G2 process design kit. In the first course offering, 19 students developed EZ130 8T, an open-source eight-track standard-cell library comprising 220 cells. We evaluate successive library versions using eight synthesis benchmarks, across which EZ130 8T achieves significant area reduction compared to the SG13G2 library at competitive timing. For a postlayout 8×8 matrix-vector multiplier, EZ130 8T reduces cell area by 35% and energy by 39% while maintaining virtually the same clock period. The library has already been adopted in other ETH Zurich VLSI courses, enabling the creation of chips entirely designed by students down to the transistor level.

[FOSS] AI IC Designs

Harald Pretl, Kevin Cameron, Jun‑ichi Okamura

FOSS AI IC Designs Examples

Intensive work over last three months was carried out by Prof. Harald Pretl together with an AI coding agent, thru which a substantial chip‑design knowledge base was built. At this stage, the AI agent is able to design, simulate, and layout a low‑noise, low‑voltage bandgap reference plus LDO with minimal manual intervention (along with many additional circuits that will be showcased later). The rapid progress in capability development is highly impressive.

The entire implementation was performed in OpenPDK 130nm CMOS using IIC‑OSIC‑TOOLS with almost no human involvement. The resulting layout is densely packed, the floorplan is coherent, and a manually created version would not differ significantly. Dummy structures were inserted for matching, and common‑centroid placement was applied to critical MOSFET devices.

Significant progress has also been achieved by Kevin Cameron, primarily on the simulation side, covering complete digital and AMS/RF domains. The work described in the linked repository has been developed and advanced accordingly, with sv2ghdl, which translates SystemVerilog RTL into VHDL for use with GHDL and NVC simulators. The generated VHDL leverages simulator extensions that go beyond what SystemVerilog offers, including multi‑UDN wires, bidirectional components, and improved unknown‑state handling

<https://github.com/kev-cam/sv2ghdl/blob/main/README.md>

A beta version of an automatic P&R tool for the OpenPDK TR‑1um was developed by Jun‑ichi Okamura using Claude AI and FOSS KLayout API and accompanying verification scripts. The flow is based on the newly updated standard‑cell library, incorporating both LEF and Liberty files, and STA analysis is now supported. Regression testing was carried out on three designs: I²C, SPI, and TD4

<https://lnkd.in/gMy3ThYm>

The synthesis and automatic P&R of TD4, an educational 4‑bit CPU, were completed by Jun‑ichi Okamura using Claude AI and the OpenPDK TR‑1um flow. A custom 8×16 register file was designed, the standard‑cell height was reduced, and a simplified Liberty (.lib) file was created to enable static timing analysis. The final chip implementation is made up of 4225 devices.

Revolution EDA Mistral AI Experiments

Revolution EDA MistralAI Experiments

by Murat Eskiyerli  

There was a recent article by Prof Razavi, where the problems of Large Language Models in identifying various analogue integrated circuit blocks were recounted.

Revolution EDA uses structured JSON data format to store design files. JSON also happens to be very easy for LLMs to parse and understand. In fact, Mistral AI has a JSON mode. Mistral AI is the latest addition to the growing number of LLMs that Revolution EDA is able to use.

We did ask a few questions to Mistral AI to test its understanding of designs in Revolution EDA and its potential to help designers. The results have been very encouraging. The future analogue integrated circuit designers will be able to use large language models like Mistral AI to quickly gain understanding of a circuit and improve on it.

The transcription below is taken exactly from the interaction with Mistral AI except for small formatting changes [read more...]

[paper] Multi-Agent Self-Evolved ABC

Cunxi Yu and Haoxing Ren

Autonomous Evolution of EDA Tools: Multi-Agent Self-Evolved ABC

In 63rd ACM/IEEE Design Automation Conference (DAC ’26)

July 26–29, 2026, Long Beach, CA

DOI: 10.1145/3770743.3804221

Abstract: This paper introduces the first self-evolving logic synthesis framework, which leverages Large Language Model (LLM) agents to autonomously improve the source code of ABC, the widely adopted logic synthesis system. Our framework operates on the entire integrated ABC codebase, and the output repository preserves its single-binary execution model and command interface. In the initial evolution cycle, we bootstrap the system using existing prior open-source synthesis components, covering flow tuning, logic minimization, and technology mapping, but without manually injecting new heuristics. On top of this foundation, a team of LLM-based agents iteratively rewrites and evolves specific sub-components of ABC following our “programming guidance“ prompts under a unified correctness and QoR-driven evaluation loop. Each evolution cycle proposes code modifications, compiles the integrated binary, validates correctness, and evaluates quality-of-results (QoR) on multi-suite benchmarks including ISCAS 85/89/99, VTR, EPFL, and IWLS 2005. Through continuous feedback, the system discovers optimizations beyond human-designed heuristics, effectively learning new synthesis strategies that enhance QoR. We detail the architecture of this self-improving system, its integration with ABC, and results demonstrating that the framework can autonomously and progressively improve EDA tool at full million-line scale.

Fig: Overview of the multi-agent self-evolving framework for ABC. Specialized LLM agents evolve distinct subsystems (flow optimization, core algorithms, and mapping), with each iteration undergoing compilation, formal CEC verification, and full QoR evaluation. A planning agent coordinates global decisions, a coding agent implements edits, and all agents follow a shared rulebase and unified evaluation pipeline to enable coordinated, correctness-preserving improvements.

Acknowledgment: The authors would like to thank Prof. Zhiru Zhang and his students for their valuable feedback and insightful discussions.
