Abstract
To strengthen the IP core’s reusability, AMBA is the on-chip bus architecture used widely for interconnection standards of SOC. In AMBA Architecture, Advanced High-performance Bus is connected to an ARM control unit, memory interface, digital signal processing(DSP) and an Advanced peripheral bus used to connect to a timer, UART, keypad, and PIO. A bridge is a standard bus-to-bus interface that helps to build the communication gap between AHB and APB. Another importance of constructing a bridge is to avoid data loss when data transfer is initiated. So keeping this in mind, the upgradation in technology, tools and methodologies has made the need for advancement in the verification environment. In this paper, presents the design and verification of the AMBA-based AHB2APB Bridge. The verification environment is developed in the Questa-sim simulator. To verify the functional and code coverage multiple test cases like Increment, Wrap Read and write cycles with different bit sizes of 4,8,16 bits are done, and 100 percent Functional & 97 percent code coverage are achieved.
