“…Test sets generated by any deterministic method like functional verification sets, RTL test sets, or gate-level ATPG test sets contain circuit specific information in the form of spatial correlations (among bits of a vector) and temporal correlations (among bits of the bit stream at an input). In [14,15], a functional analysis framework for digital signals which extracted the information from the test vectors was developed, and applications to ATPG, test compression and BIST (Build-In Self-Test) were also discussed. The experimental results showed that the method was better than the random test and weighted random test in fault coverage and test application time.…”

Code-based test vector compressions are the most capable of testing current SOCs consisted of a large number of IP cores because they do not need the structure information of the cores. However, the compression ratios of this kind of compression approaches are often lower than that of other compression methods, such as linear-decompression-based schemes and broadcast-scan-based schemes. In this paper, we propose a novel method that can greatly improve the compression ratios for code-based test vector compression techniques with affordable overheads. The method decomposes an original test set to a prominent component set and a residue set using Hadamard transform. The prominent component set can be generated easily by an additional on-chip TPG, whereas the residue set can be compressed efficiently. When testing is conducted, the compressed residue is transmitted from the tester to the CUT and decompressed by a decompressor. At the same time, the prominent component set is produced by the on-chip TPG, and then composed with the residue to restore the original test set that is at last applied to the CUT. The experimental results for seven different code-based methods on some largest ISCAS'89 circuits show that the total average compression ratio rises from 60.76% to 77.74%. The compression ratio will be further improved to 85.39% if a fault simulation tool can be used. Primary results on some ITC'99 circuitries are also provided.

“…Pseudo-Noise (PN) sequences find applications in spread spectrum communication systems [1], radar [2], clock dividers [3], system identification [4,5,6,7,8], VLSI circuit testing [9,10], test-pattern generation and for signature analysis [11], scrambling in digital broadcasting and communications [12], cryptography [13] and programmable sound generators [14]. A special class of PN sequences, called the Binary Linear Feedback Shift Register (LFSR) Sequences are generated using a simple hardware i.e.…”

Pseudo-Noise (PN) sequences are widely used in, from simple applications such as clock dividers to complex applications such as spread spectrum communication systems. Among PN sequences, maximal length (m-)sequences are very popular for communications and ranging applications, due to their desirable properties. While m-sequences are available only in limited number of lengths, the non-maximal length (NML) sequences are available in varieties of lengths. It appears that the NMLS were not investigated into, to the extent they deserve. The author conjectures that several other (noncommunications) applications might benefit from the NLM sequences. In this paper, generation and periodicity property of NLM sequences, corresponding to polynomials of degree 3 to 20 are investigated. The results are expected to create an interest among the researchers in exploring some new applications of NML sequences.
