What problem does it solve?

Automatically analyzes environment analysis documents and wrapper.sv to generate Python test function scaffolds for each RTL_BUG, enabling an LLM to fill pin drives and assertion logic.

Core Features & Use Cases

• Automatic test skeleton generation: creates a test module per RTL_BUG including DUT initialization and reset sequence.
• LLM-driven test logic: fills pin drives and assertion checks based on RTL sources and analysis logs.
• Validation and completion: enforces at least one assert per function and a final dut.Finish(), and generates a comment file if no RTL_BUG exists.
• Workflow steps: uses the Init Test File script to produce skeletons, then the LLM completes the test logic.

Quick Start

Run the init_test_file.py script to generate test file skeletons from the analysis documents.
