Abstract:-Front-end VLSI design plays a critical role in the successful development of modern integrated circuits by ensuring functional correctness and design reliability before fabrication. Register Transfer Level (RTL) modeling and verification constitute the foundation of the front-end design flow, where hardware description languages and verification methodologies are extensively employed. A wide range of commercial and open-source front-end VLSI design tools are available, each offering distinct features, strengths, and limitations. This paper presents a comparative study of widely used front-end VLSI design tools for RTL modeling and verification. The study evaluates these tools based on language support, simulation performance, verification capabilities, ease of use, scalability, and suitability for academic and industrial applications. Through qualitative and quantitative analysis, this paper highlights the effectiveness of different tools in addressing verification challenges associated with complex system-on-chip designs. The results provide valuable insights for researchers, educators, and design engineers in selecting appropriate front-end tools for efficient VLSI design and verification.
