A Large-Scale SPICE Netlist Dataset for Analog Circuits by Harnessing AI

Masala-CHAI is the first fully automated framework leveraging large language models (LLMs) to generate Simulation Programs with Integrated Circuit Emphasis (SPICE) netlists.

Automating workflow could accelerate the creation of finetuned LLMs for analog circuit design and verification. We identify key challenges in this automation and evaluate the multi-modal capabilities of state-of-the-art LLMs, particularly GPT-4, to address these issues.

This approach aims to create an end-to-end SPICE netlist generator from circuit schematic images, tackling the long-standing hurdle of accurate netlist generation. Our framework demonstrates significant performance improvements, tested on approximately 2,100 schematics of varying complexity.

Shuhai is a benchmarking-memory tool that allows FPGA programmers to demystify all the underlying details of memories, e.g., HBM and DDR4, on a Xilinx FPGA

In terms of benchmarking memory, it can be done better on FPGA, rather than on CPU/GPU. When benchmarking memory on an FPGA, the benchmarking hardware engine can directly attach to the memory such that there is no noise between the targeted memory and the benchmarking engine.

With Shuhai, before implementing the concrete application that contains a particular memory access pattern on the FPGA, we are able to benchmark the corresponding memory access pattern to make sure that the memory side will not be the bottleneck.

Generate Compilers from Hardware Models

Compiler backends should be automatically generated from hardware design language (HDL) models of the hardware they target. Generating compiler components directly from HDL can provide stronger correctness guarantees, ease development effort, and encourage hardware exploration. Past work has already championed this idea; here we argue that advances in program synthesis make the approach more feasible. We present a concrete example by demonstrating how FPGA technology mappers can be automatically generated from SystemVerilog models of an FPGA's primitives using program synthesis.

Open-source IC cells as 3D prints. A rough how-to guide

This util can interpret so called IC layouts and render them in 3D. The program accepts standard GDSII files as input data. Along with the layout file, it requires a so called process definition file which contains the 3D parameters of the process being used.

VeriGen: A Large Language Model for Verilog Code Generation

The next step getting a Verilog fine-tuned LLM to generate the RTL; then we can kick-back & watch the whole SoC emerge autonomously. Upon testing with a more diverse and complex problem set, we find that the fine-tuned model shows competitive performance against state-of-the-art gpt-3.5-turbo, excelling in certain scenarios. Notably, it demonstrates a 41% improvement in generating syntactically correct Verilog code across various problem categories compared to its pre-trained counterpart, highlighting the potential of smaller, in-house LLMs in hardware design automation.

Rosetta - Realistic High-level Synthesis Benchmark Suite for Software Programmable FPGAs

It contains six fully-developed applications from machine learning and image/video processing domains, where each benchmark consists multiple compute kernels that expose diverse sources of parallelism.

These applications are developed under realistic design constraints, and are optimized at both kernel-level and application-level with the advanced features of HLS tools to meet these constraints.
