Abstract
The present invention is an on board internal peripheral component interconnect (PCI) bus tester for testing internal components of a microelectronic chip. The present invention includes internal PCI testing agents that facilitate the application of test vectors to internal PCI agents from a minimal number of external periphery pins on the chip. The on board internal peripheral component interconnect (PCI) bus tester then captures the state of an internal PCI bus and transmits it though the external periphery pins of the chip for analysis to determine if the internal agent components are functioning correctly.
Claims8
An internal bus testing method that provides testing control and visibility of an internal PCI bus state utilizing an on board internal PCI bus tester, comprising the steps of;
- a communicating information related to test vectors between external devices and internal testing agent;
- b transmitting said information related to said test vectors to said internal PCI bus;
- c executing said test vectors over said internal PCI bus via an internal testing agent coupled to said internal PCI bus;
- and
- d capturing information related to said test vectors on said internal PCI bus via said internal testing agent coupled to said internal bus.
