VerilogCoder: Autonomous Verilog Coding Agents with Graph-based Planning and Abstract Syntax Tree (AST)-based Waveform Tracing Tool
VerilogCoder is an autonomous verilog coding agent that using graph-based planning and AST-based waveform tracing tool. The paper is in [https://arxiv.org/abs/2408.08927v1]. We use Verilog Eval Human v2 benchmarks on (https://github.com/NVlabs/verilog-eval/tree/main/dataset_spec-to-rtl) for experiments.
The prompts are finetuned for GPT-4 and Llama3. User can switch to other LLM models with their own prompts.
- Case Dir:
<project_home_dir>/hardware_agent/examples/VerilogCoder/verilog-eval-v2/ - Benchmark Dir:
<case_dir>/dataset_dumpall - VerilogCoder Generated Plan Reference Dir:
<case_dir>/plans - VerilogCoder Generated Verilog File Reference Dir:
<case_dir>/plan_output
- Input: Target RTL specification, and testbench.
- Output: Completed functional correct Verilog module.
In order to run the waveform tracing tool, user need to install iverilog.

user_task_ids = {'zero'}
case_manager = VerilogCaseManager(file_path=args.verilog_example_dir, task_ids=user_task_ids)
- Run the command for "python hardware_agent/examples/VerilogCoder/run_verilog_coder.py --generate_plan_dir <TCRG_plan_dir> --generate_verilog_dir <Verilog_code_dir> --verilog_example_dir <Verilog_Eval_v2_benchmark_dir>".
