PCI bus system testing and verification apparatus and method

The present invention relates generally to information handling systems including computer systems and related devices and, more particularly, to a method and apparatus for identifying functional problems in a PCI design via iterative testing of PCI protocol. An improved PCI verification method and apparatus provides iterative testing of all desired conditions or protocol combinations in a PCI system. One or more commands may be tested in combination with one or more functional behavior parameters throughout a desired range of variable parameter values. In one aspect, an apparatus and method for testing a PCI device for compliance under the PCI specification in target operation is provided. In another aspect, an apparatus and method for testing a PCI device for compliance under the PCI specification in master operation is provided.
