Real time automated checking mechanism for a bus protocol on an integrated bus system

摘要

A bus protocol is checked automatically during design or manufacture by connecting a bus protocol monitor to the bus and monitoring signals applied to the bus. The response to those signals is then compared with a predetermined desired response. A signal is generated to alert the protocol designer or manufacturing controller if there is an improper response that indicates that the protocol is in error. The invention is particularly useful as applied to check an LPC bus protocol.
