An Effective Deterministic BIST Scheme for Shifter/Accumulator Pairs in Datapaths
نویسندگان
چکیده
In this paper an effective Built-In Self-Test (BIST) scheme for the shifter-accumulator pair (accumulation performed either by an adder or an ALU) which appears very often in embedded processor, microprocessor or DSP datapaths is introduced. The BIST scheme provides very high fault coverage (>99%) with respect to the stuck-at fault model for any datapath width with a regular, very small and counter-generated deterministic test set, as it is verified by a comprehensive set of experiments.

Efficient BIST schemes for RNS datapaths
It has recently been shown that accumulators can be used elfciently for test pattem generation as well as for test response compaction. In this paper we present a BIST scheme for accumulators where the accumulator is simultaneously used as a test pattern generator and a response compactor during its own testing. We also show that the proposed BlST scheme is especially suitable for accumulator, ...
متن کاملAccumulator based deterministic BIST
Most built-in self test (BIST) solutions require specialized test pattern generation hardware which may introduce significant area overhead and performance degradation. Recently, some authors proposed test pattern generation on chip by means of functional units also used in system mode like adders or multipliers. These schemes generate pseudo-random or pseudo-exhaustive patterns for serial or p...

Abstract A new approach to optimize a configurable twodimensional (2-D) linear feedback shift registers (LFSR) for both embedded and random test pattern generation in built-in self-test (BIST) is proposed. This configurable 2-D LFSR based test pattern generator generates: 1) a deterministic sequence of test patterns for random-pattern-resistant faults, and then 2) random patterns for random-pat...
متن کاملAccumulator-based built-in self-test generator for robustly detectable sequential fault testing - Computers and Digital Techniques, IEE Proceedings-
In this paper an algorithm for the generation of single input change (SIC) pairs is presented, termed the accumulator-based SIC pair generation (ASG) algorithm; SIC pairs have been effectively utilised for testing robustly detectable sequential faults. ASG is implemented in hardware utilising an accumulator whose inputs are driven by a barrel shifter. Since such structures (accumulators whose i...
متن کاملTest Pattern Generation Using Pseudorandom Bist
Pseudorandom built-in self test (BIST) generators have been widely utilized to test integrated circuit and systems. In this Project an accumulator-based-3 weight test pattern generation scheme is presented and proposed scheme generates set of test patterns with weights 0, 0.5 and 1. These accumulators are mostly found in current VLSI chips and that the scheme can be efficiently to drive the har...
