Abstract: 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.

Key words: Asynchronous Transfer Mode(ATM), switch control circuit, functional verification
