Engineering Research Equipment Grant: (VLSI Testing Equipments)

点击翻译按钮获取中文摘要

Equipment is obtained that is required to perform testing on VLSI chips and this equipment consists of two parts. The first part is a logic analysis system which includes a logic analyzer and a pattern generator. The pattern generator generates a sequence of test vectors which are then fed into the unit under test. The outputs of the logic analyzer are used to detect errors in the chip (only at the logic level). The second part of testing is at the physical level which requires a probing station system. This system has probes which can access almost every part of the chip. Signals are fed in and out of the chip and a particular part of the chip can be isolated. The Hewlett Packard 163OG is the logic analyzer to be used and the 600-MZ analytical test station from micro-tec West, Inc., forms that major portion of the probing system. The VLSI testing station will be used to check chips for communication and signal processing systems, in particular, a concatenated coding system.
