VerilogEval-v2-NTU

This repository provides the patched version of VerilogEval-v2's dataset_spec-to-rtl, a benchmark designed to evaluate the capabilities of large language models in digital design and hardware description languages. The original VerilogEval-v2 dataset was developed by NVLabs and is available at https://github.com/NVlabs/verilog-eval under the MIT License.

All patches are located in the patches directory and are generated by create_patch.sh. The file data/train-00000-of-00001.parquet contains the patched dataset, which also includes the unmodified problems.

Patches Descriptions

• Initialization and Reset Handling: We removed non-synthesizable initial blocks from all reference designs. To ensure proper register initialization, we introduced an explicit reset signal and updated the corresponding problem prompts.
  • Patched Problems: 34, 53, 66, 104
• Synthesizability and Logic Corrections: In several problems, the reference designs produced unsynthesizable high-impedance or undefined outputs. We rewrote these modules to adhere to standard synthesizable SystemVerilog conventions.
  • Patched Problems: 116, 124, 151, 156
• Specification Alignment and Disambiguation: We resolved inconsistencies between prompts and implementations. For Problem 62, the module logic was corrected to match the selection requirement (selecting a or b when sel is 1). For Problem 63, we explicitly defined the shift register's direction in the prompt to eliminate ambiguity.
  • Patched Problems: 62, 63
• FSM and Interface Refinement: For problems involving Finite State Machines (FSMs) and complex interfaces, we refined the descriptions to clarify state transition conditions and port declarations, removing extraneous information.
  • Patched Problems: 89, 93, 123, 134
• Naming Standardization: We corrected naming inconsistencies to ensure uniform testing. This includes fixing port mappings in Problem 99 (correcting Y2/Y4 to Y3/Y1) and resolving top-module naming issues in Problem 131.
  • Patched Problems: 99, 131
