Overview

The AMBA bus protocol is a widely used on-chip interconnect specification for the connection and management of functional blocks in a System-on-Chip (SoC). The APB (Advanced Peripheral Bus) is a simpler bus protocol, which is used for connecting lower-bandwidth peripherals to the higher-performance main system bus.

This project aims to provide a comprehensive implementation and verification of the AMBA3 and AMBA4 APB protocols, including:

1. Digital Design: The digital design of the AMBA3 and AMBA4 APB bus interfaces, including the master, slave, and bridge components.
2. Verification: Thorough verification of the APB protocol implementation using SystemVerilog and the Verilog Hardware Description Language (HDL).

Features

AMBA3 APB Protocol Features:

• PSLVERR: An error signal to indicate the failure of a transfer.
• PREADY: A ready signal to indicate completion of an APB transfer.

AMBA4 APB Protocol Features:

• PPROT: A protection signal to support both non-secure and secure transactions on APB.
• PSTRB: A write strobe signal to enable sparse data transfer on the write data bus.
