Physical design implementation of 32-bit AMBA ASB APB module with improved performance

The Advanced Microcontroller Bus Architecture (AMBA) is used for system on chip representation for high-performance embedded microcontrollers. This paper reports on the physical design implementation of AMBA Advanced System Bus (ASB) and Advanced Peripheral Bus (APB) bridge module. Further, three bit ripple counter has been used to minimize the clock skew. For modeling and simulation ModelSim Version 10.3 is used and also test benches are designed for this purpose. Xilinx-ISE design suite is used to extract synthesis and design utilization summary, RTL Compiler for the Synthesis and Encounter Digital Implementation System is used for the physical design. It has been shown that efficient design of system clock leads to faster operation and better utilization of system resources.
