We present a design for a low-cost, functional VLSI chip tester. It is based on the Apple Macintosh II personal computer. It tests chips that have up to 128 pins. All pin drivers of the tester are bidirectional; each pin is programmed independently as an input or an output. The tester can test both static and dynamic chips. Rudimentary speed testing is provided. Chips are tested by executing C ...

we find an explicit expression of the tutte polynomial of an $n$-fan. we also find a formula of the tutte polynomial of an $n$-wheel in terms of the tutte polynomial of $n$-fans. finally, we give an alternative expression of the tutte polynomial of an $n$-wheel and then prove the explicit formula for the tutte polynomial of an $n$-wheel.

Preliminary -The BERTScope BSX-series Bit Error Rate Tester introduces a receiver test platform capable of supporting emerging Gen4 standards and beyond. With the addition of powerful data processing and internal Tx equalization, the BERTScope supports protocol-based handshaking and synchronization with your device under test (DUT), including interactive link training at data rates up to 32 Gb/...

Key performance specifications Up to 1.6 Gb/s Pattern Generator/Error detector for fast, accurate characterization of digital communications signaling systems PRBS or 8 Mb user-defined patterns provide the versatility to debug or verify any combination of digital signaling ANSI jitter measurements (RJ, DJ, and TJ) to measure the impact of random and deterministic jitter on the total jitter at B...

Die Aufgaben, die ein Software-Tester zu erledigen hat, gehören bei vielen in der Softwareproduktion tätigen Personen zu den weniger attraktiven. Testen wird oft noch als notwendiges Übel am Ende der Softwareerstellung angesehen. Das Berufsbild des Testers ist nicht sehr angesehen und wird von den meisten nicht angestrebt. Diese Sichtweise steht allerdings im krassen Widerspruch zur Bedeutung d...

Abstract The Gyrover is a single wheel gyroscopically stabilized mobile robot developed at Carnegie Mellon University. An internal pendulum serves as a counter weight for a drive motor that causes fore/aft motion, while a large gyroscope on a tilt-mechanism provides for lateral balance and steering actuation. In this paper, we develop a detailed dynamic model for the Gyrover, and use this model...

We present an adaptive tester for the unateness property of Boolean functions. Given a function f : {0, 1}n → {0, 1} the tester makes O(n log(n)/ε) adaptive queries to the function. The tester always accepts a unate function, and rejects with probability at least 0.9 if a function is ε-far from being unate.
