Abstract: A system for testing integrated circuit chips is comprised of a pattern generator that is coupled to a memory which stores variable length instructions that specify sets of bit streams for testing the chips. Each variable length instruction includes a code which indicates the number of bit streams in the set. Each bit stream in the set consists of a selectable number of bits which start on a word boundary and vary in increments of one bit. If the code indicates that the number of bit streams in a set is only one, then that one bit stream is stored in consecutive words of the memory. If the code indicates the number bit streams in a set is more than one, then those multiple bit streams are stored in an interleaved fashion in consecutive words in the memory. A respective series of unused bits starts immediately after each bit stream and ends on a word boundary.

Abstract: An adaptive delay learning algorithm is presented that reduces the amount of delay before making test measurements in an automated test that requires a delay of any type to be completed before a measurement is made in order to remove the possibility that a tester component lying in the measurement path has not achieved a ready state. In the execution of an automated test, a current delay time is set to an initial delay value. Test execution does not begin until the current delay time elapses. If, upon execution, the test fails, the current delay time is set to a different delay time, and the test is reexecuted only after the updated current delay time has elapsed.

Abstract: An apparatus enables development and debugging of a control program for controlling a relatively small product having rapid response without using an actual mechanism. A simulation unit simulates an operation of a mechanism, in a simulation cycle shorter than a control cycle, for a time corresponding to the control cycle, and outputs a state variable of the mechanism to a holding circuit. When the state variable is held in the holding circuit, asimulation control unitmakes the simulation unit shift to a response waiting state and makes a control program executing unit calculate a controlled variable. When the controlled variable is held in the holding circuit, the simulation control unit makes the control program execution unit shift to a response waiting state and makes the simulation unit initiate a simulating operation. The apparatus is applied when a control program for every product requiring a precise servo control is developed.

Abstract: A method and apparatus for controlling a test track system for motor vehicles having at least one test station and a device for carrying out this method (European system), which allows a high utilization of the capacity of the test track system. This can be accomplished, for example, by the fact that the system can automatically make an unambiguous identification of the vehicle and an unambiguous identification of the tester at each testing section. Thus all the information compiled by the test stations is automatically allocated to the current vehicle being tested. This makes it possible for the tester to move the vehicle from one test road to another, for example, without having to initialize the system again at the new test road. The system recognizes automatically that the vehicle is being tested further in the second test road, for example.

Other software components may also be tested including menu structures. A definition of the menu structure is rigorously traversed such that each entry of each menu is thoroughly tested and reported. Results are automatically compared and verified against known good results or test results are automatically reviewed. Both transaction testing and menu testing may be incorporated into regression testing.
