ATM交换控制电路设计验证技术

Verification Technology of ATM Switch Control Circuit Design

异步传输模式(ATM)技术作为宽带应用的基本技术用在局域网和广域网中。该文结合ATM技术应用,以ATM交换机的一组芯片设计为研究对象,针对其中一款ATM交换控制电路的FPGA原型,提出一种基于Tcl语言的自动化验证方法,实现ATM交换控制电路的功能验证。应用结果表明:话音业务和IP业务均通信正常,中继信令测试正常。

The technology of Asynchronous Transfer Mode（ATM） is used in Wide Area Network（WAN） and Local Area Network（LAN） as a basic technology for the application of broad band. In this paper, with the application of ATM technology, an ATM switch chip set is referred to as an object under research. Aiming at the FPGA prototype of an ATM switch control circuit which is one of the chip set, a method of automated verification based on Tcl is advanced and functional verification of the ATM switch control circuit is accomplished. The application test shows that the voice service and the IP service are all working in order in communication and the test result of relay signaling is correct.
