The paper discusses the challenges and opportunities in conversational hardware design using language models. It mentions the use of ML-enhanced code completion tools like GPT-4 and HuggingChat for designing hardware. It also highlights the availability of tools like OpenLane, Tiny Tapeout, and Icarus Verilog for hardware design. The paper emphasizes the importance of human feedback in training language models and mentions the potential benefits of using conversational language models in hardware design. It discusses the limitations and challenges of using conversational language models, such as the need for large training data and the difficulty in reproducing results. The paper concludes by suggesting steps for practical adoption of conversational language models in hardware design. The processor datapath was assembled in Conversation 08 and assembly programs were written by ChatGPT. The Python assembler was written in Conversation 09 and high-quality code was produced. The processor implementation was evaluated and the total time budget was 22.8 hours. The processor design included control signals, memory mapping, and instructions with variable-data operands. The design process involved task partitioning, conversation threading, and co-design with ChatGPT-4. Simulation and testing were used to find bugs and make updates to the design. The overall goal was to co-design an 8-bit accumulator-based microprocessor. The design task was constrained by space and I/O limitations. The conversation flow involved 11 conversation threads across 18 topics. The study aimed to investigate the potential of unstructured conversations with language models in the hardware design process. The document discusses challenges and opportunities in conversational hardware design. It focuses on the performance of two language models, ChatGPT-3.5 and ChatGPT-4, in generating Verilog code and testbenches for specific hardware designs. The results show that ChatGPT-4 performed better than ChatGPT-3.5 in creating functioning testbenches, although both models struggled with certain aspects of the design process. The document provides examples of conversations and code excerpts to illustrate the challenges faced and the improvements made. Overall, the study highlights the potential of conversational AI in assisting with hardware design but also emphasizes the need for human intervention and review to ensure compliance and accuracy. This summary explores the challenges and opportunities in conversational hardware design. It evaluates four conversational language models (LLMs) and their output in less constrained scenarios. The benchmarks used in the evaluation are described in Table I. The study considers real-world design constraints and the limitations of the Tiny Tapeout toolflow. The methodology involves conversational prompts for verification and the use of human feedback to address errors. The conversation flow and success/failure criteria are outlined in Figure 2. The potential of instruction-tuned conversational models for hardware design is discussed. The paper highlights the need for standardized interfaces and the benefits of large language models (LLMs) in hardware design. It also mentions related works in the field and provides an overview of LLMs and their capabilities. The contributions of the study include the evaluation of LLMs in hardware design and the development of benchmarks to assess their capabilities. The paper concludes by emphasizing the importance of integrating LLMs into the hardware design process and addressing the challenges associated with their adoption in the hardware domain.
