The AHB2APB Bridge is a critical component in many SoC architectures, enabling communication between high-performance AHB masters and low-speed APB peripherals. This module manages protocol conversion while maintaining data integrity and timing requirements.
Understand the architecture and purpose of AHB and APB interfaces.
Design a functional AHB2APB bridge from scratch using Verilog HDL.
Cover key design aspects:
Address decoding and transfer mapping between AHB and APB
Transfer handshaking and state machines
Handling write/read operations, including wait states and error signaling
Synthesize and simulate the bridge design using tools like Vivado or ModelSim.
Implement timing constraints and basic static timing analysis.
Develop a robust testbench for validating the AHB2APB bridge functionality.
Write SV test scenarios to validate:
Correct transaction conversion from AHB to APB
Read-after-write integrity
Error response handling and protocol corner cases
Use assertions and functional coverage to ensure exhaustive verification.
Apply scoreboarding and protocol checking to confirm expected data transfer.
Ability to design a protocol bridge essential for SoC interconnects.
Strong hands-on experience in verifying communication between two protocols.
Deep understanding of AHB & APB signaling and their integration.
Preparedness for real-world RTL design and verification roles.
