چکیده

The paper presents a method for testing a system-on-achip by using a compressed representation of the patterns on an external tester. The patterns for a certain core under test are decompressed by reusing scan chains of cores idle during that time. The method only requires a few additional gates in the wrapper, while the mission logic is untouched. Storage and bandwidth requirements for the ATE are reduced significantly.

Variable Length Dynamic Shifting Based Lfsr Multiple Scan Chain For Test Compression

The project presents a test pattern compression method for circuits with a high number of parallel scan chains .It reduces test time while it keeps hardware overhead low. The decompression method is based on the continuous LFSR reseeding that is used in such a way that it enables LFSR lockout escaping within a small number of clock cycles. It requires a separate controlling of the LFSR de-compr...

Test data compression and decompression based on internal scan chains and golomb coding - Computer-Aided Design of Integrated Circuits and Systems, IEEE Transactions on

We present a data compression method and decompression architecture for testing embedded cores in a system-on-a-chip (SOC). The proposed approach makes effective use of Golomb coding and the internal scan chain(s) of the core under test and provides significantly better results than a recent compression method that uses Golomb coding and a separate cyclical scan register (CSR). The major advant...

Integrated Test Data Decompression and Core Wrapper Design for Low-Cost System-on-a-Chip Testing

This paper discusses an integrated solution for reducing the volume of test data for deterministic system-on-achip testing. The proposed solution is based on a new test data decompression architecture which exploits the features of a core wrapper design algorithm targeting the elimination of useless test data. The compressed test data can be transferred from the automatic test equipment to the ...

Deterministic Test Vector Compression/Decompression for Systems-on-a-Chip Using an Embedded Processor

A novel approach for using an embedded processor to aid in deterministic testing of the other components of a system-on-a-chip (SOC) is presented. The tester loads a program along with compressed test data into the processor’s on-chip memory. The processor executes the program which decompresses the test data and applies it to scan chains in the other components of the SOC to test them. The pro...

Deterministic BIST with multiple scan chains

A deterministic BIST scheme for circuits with multiple scan paths is presented. A procedure is described for synthesizing a pattern generator which stimulates all scan chains simultaneously and guarantees complete fault coverage. The new scheme may require less chip area than a classical LFSR-based approach while better or even complete fault coverage is obtained at the same time.
