METHOD AND APPARATUS FOR HIGH SPEED INTEGRATED CIRCUIT TESTING

摘要

An apparatus for use in high speed digital testing of high pin count logic circuits is provided wherein a plurality of terminal electronics units (12) are connected in series to each other and to one channel (13) of a multi-channel tester. Each terminal electronics unit (12) stores a test vector from the test channel in a first mode, and applies the test vector to the circuit under test at high speed in a second mode. Each pin electronics unit can also store response data from the circuit under test.
