ABSTRACT
Advanced Extensible Interface (AXI) is the most commonly used bus protocols in the day-to-day because of its high performance and high-frequency operation without using complex bridges. AXI is also backwardcompatible with existing AHB and APB interfaces. So verification of driver logic using AMBA-AXI UVM is presented in this paper. The AXI is used for multiple outstanding operations which is only possible in the other protocol but it is possible in AXI because it contains different write address and data channels and AXI also supports out of order transfer based on the transaction ID which is generated at the start of the transfer. The driver logic for the AXI has been designed and implemented using the Universal Verification Methodology (UVM).The signaling of the five channels such as write address, write data, write response, read address, read data channel of AXI protocol are considered for verification. According to the AXI protocol,the signals of these channels are driven to the interconnect and results are observed for single master and single slave. The driver logic has been implemented and verified successfully according to AXI
protocol using the Rivera Pro. The results observed for single master and single slave have shown the correctness of AMBA-AXI design in Verilog.
