An OCP-AHB bus wrapper with built-in ICE support for SOC integration

Abstract

As the design of SoC is getting more and more complicated, the IPs (Intellectual Property) reuse ability increasing is the key issue to improve the time of the embedded systems development and integration. However, the different SoC design environment will affect the IPs reuse ability, such as in different system bus. In this paper we have implemented a standard OCP-AHB bus wrapper. By this wrapper, the IP with OCP interface can connect to AMBA 2.0 AHB bus quickly, and IP designer can focus on the development of IP functionalities without considering the data transaction in different interconnects. This will reduce the IPs development time, and increase the reuse ability. Thus the system integration and verification can be accelerated. Furthermore, we added the built-in ICE architecture to make the SoC verification more flexible and quickly.
