VLSI verification plays a pivotal role in ensuring the reliable functionality of integrated circuits (ICs). This paper delves into the investigation of the Advanced Peripheral Bus (APB) and Advanced High-performance Bus (AHB Lite) protocols, which are essential components in IC communication. The focal point of this study is the critical aspect of data transfer between master and slave cells. Both APB and AHB Lite protocols are instrumental in streamlining communication processes. The paper provides an in-depth understanding of these protocols and evaluates their efficiency in transmitting data from master to slave. The research emphasizes the importance of selecting a protocol that enables higher data transfer speeds, offers multiple transmission modes, ensures data security, and minimizes power consumption. The ultimate goal of this investigation is to identify protocols that enhance VLSI verification by optimizing IC communication. By uncovering the strengths and weaknesses of APB and AHB Lite, this study aims to contribute valuable insights into the selection and implementation of communication protocols for advanced integrated circuits.
