OpenTimer - a High-Performance Timing Analysis Tool for VLSI Systems.

OpenTimer is a new static timing analysis (STA) tool to help IC designers quickly verify the circuit timing. It is developed completely from the ground up using C++17 to efficiently support parallel and incremental timing.

Features:
▫️Industry standard format (.lib, .v, .spef, .sdc) support
▫️Graph- and path-based timing analysis
▫️Parallel incremental timing for fast timing closure
▫️Award-winning tools and golden timers in CAD Contests

▫️Maintain the same file consistency between simulation and synthesis for different tools
▫️Share the same HDL source code base and IP cores for various FPGA projects
▫️Integration with CI and CD like Jenkins, Hudson, GitLab, etc.
▫️Run RTL unit tests under ctest: pass/fail, time execution, timeout, parallel execution, tests selection
▫️Run the same unit tests with different parameters
▫️Easy to integrate with other projects as git submodule
▫️Custom UVM printers: JSON
▫️Modern HDL testing library written in C++11 using UVM-SystemC
▫️Support for Clang 3.5+

BENDER - a dependency management tool for hardware design projects written in Rust.

It provides a way to define dependencies among IPs, execute unit tests, and verify that the source files are valid input for various simulation and synthesis tools.

Principles
▫️Be as opt-in as possible
▫️Allow for reproducible builds
▫️Collect source files
▫️Manage dependencies
▫️Generate tool scripts

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.

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.
