Design and Implementation of AHB to APB Bridge using Verilog

Efficient on-chip communication is vital in modern embedded and System-on-Chip (SoC) architectures. This project presents the design and implementation of an AHB (Advanced High-performance Bus) to APB (Advanced Peripheral Bus) bridge using Verilog Hardware Description Language (HDL). The bridge serves as an interface between high-speed AHB masters and low-speed APB peripherals, with a Finite State Machine (FSM) governing the control flow—including address decoding, data transfer, and handshake signal management. The Verilog-based design emphasizes modularity, timing accuracy, and hardware compatibility, making it well-suited for both FPGA prototyping and ASIC integration. Functional simulation and synthesis validate the bridge’s correctness, performance, and efficient resource utilization. The FSM-based control ensures predictable and reliable communication across the AHB and APB domains, fulfilling the structured connectivity demands of AMBA-based SoC designs [1].
