Low-Power Programmable PRPG With Test Compression Capabilities

This paper describes a low-power (LP) programmable generator capable of producing pseudorandom test patterns with desired toggling levels and enhanced fault coverage gradient compared with the best-to-date built-in self-test (BIST)-based pseudorandom test pattern generators. It is comprised of a linear finite state machine (a linear feedback shift register or a ring generator) driving an appropria...
