# VeriCoder: Enhancing LLM-Based RTL Code Generation through Functional Correctness Validation

This repository hosts **VeriCoder**, a model presented in the paper [VeriCoder: Enhancing LLM-Based RTL Code Generation through Functional Correctness Validation](https://huggingface.co/papers/2504.15659).

VeriCoder is a model for Register Transfer Level (RTL) code generation fine-tuned on a dataset validated for functional correctness. This fine-tuning dataset is constructed using a novel methodology that combines unit test generation with feedback-directed refinement. Given a natural language specification and an initial RTL design, a teacher model iteratively revises the RTL design based on simulation results using generated tests. Every example in the dataset is functionally validated, consisting of a natural language description, an RTL implementation, and passing tests.

For more details and code, visit the [GitHub Repository](https://github.com/Anjiang-Wei/VeriCoder).

## Key Highlights

-   **Functionally Validated Dataset**: 125,000+ examples with simulation-passing RTL designs.
-   **Feedback-Driven Construction**: Iteratively refine designs and tests based on test results.
-   **Superior Performance**: Achieves up to +71.7% relative improvement on VerilogEval benchmarks.
-   **Comprehensive Resources**: Includes dataset, model weights, inference scripts, and training pipeline.
