Abstract: A method for monitoring communications between a device under test (DUT) and an automated test equipment (ATE) is disclosed. The method comprises programming an interface core and a protocol analyzer module onto a programmable logic device, wherein the programmable logic device is controlled by a system controller and is operable to generate commands and data to test a DUT, wherein the interface core is operable to generate signals to communicate with the DUT using a protocol associated with the DUT. The method also comprises monitoring data and command traffic associated with the protocol in the interface core using the protocol analyzer module and storing results associated with the monitoring in a memory comprised within the protocol analyzer module. The method finally comprises transmitting the results upon request to an application program associated with the protocol analyzer module executing on the system controller.

Abstract: The present invention is directed to the synchronous control of a parallel interface. In particular, the present invention provides an interface between a serial communication link and parallel communication channels within an adapter that operate synchronously, and without requiring a data buffer. A data buffer may be provided between the parallel data channels of the adapter that operate synchronously with the serial data channel, and the adapter's host interface. The present application reduces the amount of memory that must be provided by the adapter, and eliminates delays caused by the provision of additional data buffers.

Abstract: An automated software testing system for testing system-under-test resident software without extensive intrusion into the system-under-test hardware or software. A first version of interactive software is executed on the system-under-test. During execution all input signals to the system-under-test such as mouse activities and keystrokes are recorded by the testing system as a script. Additionally, selected system-under-test display images are captured by the testing system. Subsequently, a second version of the interactive software is executed on the system-under-test and the previously recorded script is played back. The images generated by the second version of software are compared to the images generated by the first version of software and the differences are displayed.
