Patent 7590903 was granted and assigned to Verigy on September, 2009 by the United States Patent and Trademark Office.
An adaptive test system includes one or more reconfigurable test boards, with each test board including at least one re-configurable test processor. The re-configurable test processors can transmit communicate with one another using an inter-processor communications controller associated with each re-configurable test processor. The communications include configuration information, control information, communication protocols, stimulus data, and responses. Configuration information and stimulus data can also be read from a memory. Configuration information is used to configure one or more re-configurable test processors. Once configured, the re-configurable test processor or processors process the data in order to generate one or more test signals. The one or more test signals are then used to test a DUT.
