The AHB to APB bridge is an AHB slave and the only APB master which provides an interface between the highspeed AHB and the low-power APB. Read and write transfers on the AHB are converted into equivalent transfers on the APB.
The bridge performs address mapping between the AHB address space and the APB address space. It translates AHB addresses to appropriate APB addresses, ensuring that the correct peripherals are selected and accessed. The bridge handles data transfer between the AHB and APB buses.
To design and simulate a synthesizable AHB to APB bridge interface using Verilog and run single read and single write tests using AHB Master and APB Slave testbenches. The bridge unit converts system bus transfers into APB transfers and performs the following functions: Latches the address and holds it valid throughout the transfer.
The AHB to APB bridge is an AHB slave, providing an interface between the high speed AHB and the low-power APB. Read and write transfers on the AHB are converted into equivalent transfers on the APB. As the APB is not pipelined, then wait states are added during transfers to and from the APB when the AHB is required to wait for the APB.
AHB to APB Bridge FSM is use for communication between AHB protocol and APB Protocol. The State machine of AHB to APB Bridge FSM is shown in Fig 4.1.AHB to APB bridge State machine has 8 states.
The AHB2APB bridges the gap between AHB and APB. It buffers the AHB's address, controls, and data, drives the APB peripherals, and sends data and a response signal back to the AHB [4]. The AHB2APB interface is intended to work when the AHB and APB clocks have any frequency and phase combination. TheAHB2APB transfers data from the AHB to the APB for
In this project, I have developed synthesizable design of AHB to APB Bridge and test bench for the functional verification of the same in Verilog HDL. TEAM ID: 262252
This work focuses on functional verification of AMBA AHB to APB Bridge protocol for completeness by employing System Verilog layered testbench architecture. This ensures complete verification of functionality with maximal coverage.
This repository offers a comprehensive collection of Verilog netlist code aimed at the design and verification of an AHB (Advanced High-Performance Bus) to APB (Advanced Peripheral Bus) bridge.
Bridges are common bus-to-bus interconnections that make uniform interconnection across IP addresses belonging to various buses. we created a testbench and comprehensible design for the AHB to APB bridge in this project so that it could be functionally verified in Verilog HDL. Xilinx 14.7 ISE is the software tool that we have utilized.
