Design and Analysis of APB and AHB Lite Protocol

The Verification is very crucial in the VLSI segment. APB and the AHB Lite protocols are the prime focus in this paper. The AMBA consists of the APB (Advanced Peripheral Bus) and the AHB (Advanced High-performance Bus). Unlike the AHB, APB follow the non-pipelined convention. Inside the IC communication takes place between the master and the slave using both the models. Verilog language and testbench is used to perform synthesis and design. The data transfer is the most critical aspect that is very important in the communication process involving the master and the slave cells of the IC. Both APB and the AHB deal with the communication itself. The basic understanding of the APB and the AHB protocol is dealt with here and how efficiently the data is transmitted from the master to the slave is seen. We should always use a protocol that will transfer data at a higher speed, offer more modes of transmission, provide security to the data that is being transmitted and also ensure that less power is consumed in the entire process. If a protocol can satisfy all of the above properties, then it is ideal to use that protocol for our communication.
