Abstract: A simulation system is provided for simulating operation of a plurality of hardware devices in combination with an instruction set simulator simulating execution of program instructions by a program core. A test scenario manager acts as a master and serves to command the hardware devices and the instruction set simulator with stimulus signals to simulate various specified activity.

Abstract: A hardware simulation and validation system is provided using a plurality of signal interface controllers to exchange stimulus and response signals with a hardware simulation. The action of the signal interface controllers is coordinated by a test scenario manager which exchanges test scenario controlling messages with the signal interface controllers. The test scenario controlling messages specify simulation actions to be performed and when those simulation actions are to be performed.

Abstract: The present invention provides a system and method for testing compliance of a device with a bus protocol. The method comprises the steps of reading a configuration file containing predetermined parameters identifying the type of device and capabilities of the device, and then employing a configuration engine to dynamically generate a test environment for the device by creating selected test components which are coupled via the bus with a representation of the device to form the test environment, the test components being selected dependent on the configuration file. A test sequence is then executed, during which signals passed between the representation of the device and one or more of the test components are monitored to generate result data indicating compliance with the bus protocol. This approach has been found to provide a particularly user friendly and efficient approach for testing compliance of devices with a bus protocol.

Abstract: A verification environment is provided that co-verifies a software component 8 and a hardware component 10. Within the same environment using a common test controller 18 both hardware stimuli and software stimuli may be applied to their respective simulators. The response of both the software and the hardware to the simulation conducted can be monitored to check for proper operation.

Abstract: An improved electrical test probe has a electrically conductive strain relief adapter mounted on a substrate for accepting a conductive cable having a central conductor and an outer shielding conductor separated by a dielectric layer. The conductive cable is inserted into the strain relief adapter with the outer shielding conductor in electrical contact with the adapter. The substrate is disposed within an electrically conductive elongate hollow body with the body being deformed proximate the location of the strain relief adapter to secure the substrate in the body and to provide electrical continuity between the outer shielding conductor and the substrate and the outer shielding conductor and the hollow body. The adapter further provides strain relief for the center conductor of the conductive cable and mechanical support for the substrate.
