In an interactive driving simulation apparatus for a two-wheeled vehicle, a real-time test drive performance by a student operator around a simulated driving route sequence is recorded. The recorded performance is later replayed for the benefit of the student, to provide real-world simulation, education, and performance evaluation.

The present invention provides for a method and apparatus for comparison of network systems using live traffic in real-time. The inventive technique presents real-world workload in real-time with no external impact (i.e. no impact on the system under test), and it enables comparison against a production system for correctness verification. A preferred embodiment of the invention is a testing tool for the pseudo-live testing of CDN content staging servers, According to the invention, traffic between clients and the live production CDN servers is monitored by a simulator device, which then replicates this workload onto a system under test (SUT). The simulator detects divergences between the outputs from the SUT and live production servers, allowing detection of erroneous behavior. To the extent possible, the SUT is completely isolated from the outside world so that errors or crashes by this system do not affect either the CDN customers or the end users. Thus, the SUT does not interact with end users (i.e., their web browsers). Consequently, the simulator serves as a proxy for the clients. By basing its behavior off the packet stream sent between client and the live production system, the simulator can simulate most of the oddities of real-world client behavior, including malformed packets, timeouts, dropped traffic and reset connections, among others.

A system and method to operate an electronic device, such as a memory chip, in a test mode using the device's built-in ODT (on die termination) circuit is disclosed. One or more test mode related signals, which include on-die signals and other relevant information, may be transferred from the integrated circuit of the electronic device to an external processor using the device's ODT circuit instead of the output data signal driver circuit. Therefore, no capacitive loading of output drivers occurs during test mode operations. Thus the speed of the output data path (i.e., the circuit path propagating non-test mode related signals from the electronic device to other external units in the system) is not affected by test mode operations, allowing a system designer to increase the speed of the data output path as much as desired. Further, deterioration in the quality of signals output from the output drivers is also avoided. Also, the use of a minimal number of logic gates along with the existing ODT circuits to perform transmission of test mode related signals substantially maximizes chip real estate utilization without waste. Because of the rules governing abstracts, this abstract should not be used to construe the claims.
