Abstract :
A fully integrated approach is presented for building the pin electronics portion of a VLSI functional tester. The system implements the output vector timing and formatting functions, as well as the input sampling and comparison operations. A computer-controlled feedback loop is employed to obtain a timing accuracy of better than 1 ns. Novel circuit designs are shown which make the circuit suitable for fabrication in a high-density MOS technology. An experimental chip using these techniques was fabricated in 2- mu m CMOS technology and functioned at over 30 megavectors per second.<>
