Test Time Minimization for Hybrid BIST with Test Pattern Broadcasting
نویسندگان
چکیده
This paper describes a hybrid BIST architecture for testing core-based systems together with a method for test time minimization. The approach uses test pattern broadcasting for both pseudorandom and deterministic patterns. To overcome the high complexity of the test time minimization problem we propose a fast algorithm to find an efficient combination of pseudorandom and deterministic test sets under given memory constraints. The efficiency of the approach is demonstrated by experimental results.

An Iterative Approach to Test Time Minimization for Parallel Hybrid BIST Architecture
This paper presents an approach to the test time minimization problem for parallel hybrid BIST with test pattern broadcasting in core-based systems. The hybrid test set is assembled from pseudorandom test patterns that are generated online and deterministic test patterns that are generated off-line and stored in the system. The pseudorandom patterns are broadcasted and applied to all cores in p...

This paper presents a solution to the test time minimization problem for core-based systems that contain sequential cores with STUMPS architecture. We assume a hybrid BIST approach, where a test set is assembled, for each core, from pseudorandom test patterns that are generated online, and deterministic test patterns that are generated offline and stored in the system. We propose a methodology ...

In the Reconfigurable System-On-a-Chip (RSOC), an FPGA core is embedded to improve the design flexibility of SOC. In this paper, we demonstrate that the embedded FPGA core is also feasible for use in implementing the proposed hybrid pattern Built-In Self-Test (BIST) in order to reduce the test cost of SOC. The hybrid pattern BIST, which combines Linear Feedback Shift Register (LFSR) with the pr...
متن کاملA Modified Clock Scheme for a Low Power BIST Test Pattern Generator
In this paper, we present a new low power BIST test pattern generator that provides test vectors which can reduce the switching activity during test operation. The proposed low power/energy BIST technique is based on a modified clock scheme for the TPG and the clock tree feeding the TPG. Numerous advantages can be found in applying such a technique. The fault coverage and the test time are roug...
