摘　　要：电路仿真对于电信网向分组交换网的平稳过渡有着重要意义。文章根据相关标准提出并实现了一种电路仿真专用芯片的设计方案,并对其中主要功能模块和关键算法作出了详细说明,包括一种全数字的自适应时钟恢复方法、动态深度缓冲算法等。目前该设计已经通过了验证和在实际网络环境中的测试。Circuit emulation provides a seamless migration approach to backbone PSNs without interruption of legacy services. In this paper, the design of a specific chip for circuit emulation based on IP is put forward and realized and the main functional modules and the key algorithms including an all-digital adaptive clock recovery method and a dynamic depth buffer algorithm are described in detail. The design has been verified and tested in actual networks.
