A design's increasing density, as well as its number of embedded memories increases its vulnerability to a variety of potential manufacturing defects. Standard March test algorithms used for obtaining good defect coverage must be augmented by new alg

Today’s ASIC designs consist of more memory in terms of both area and number of instances. The shrinking of geometries has an even greater effect upon memories due to their tight layouts. These two trends are putting much greater demands upon memor

The TMS370 family of microcomputers was designed with a requirement for >99% stuck fault coverage. A design for testability (DFT) methodology called parallel/serial scan design was used which partitioned the design into independently testable modules

Functional tests and I/sub DDQ/ tests are studied to determine their effectiveness toward screening failures. A model is presented for curve fitting correlation data between fault coverages and defect quality employing the Williams and Brown defect l

Unknown values result from floating and contention type faults on tristate buffer nets thereby causing MISR signature loss during test pattern compression. A Consistently Dominant Fault model is presented that removes the problem and permits fault de

The Texas Instruments TMS370 is in volume production. Sample manufacturing data has been collected to correlate stuck fault grades to the defect levels that would have been realized at those grades, at both the module and chip levels. Since the chip

The Disturb Test Algorithms are targeted for row adjacent coupled defects that can be time elapsed dependent. A BIST design is described for application of these tests for testing 256 Meg SDRAM chips.

The TMS320C80 is a programmable, parallel processing DSP. The test approach was an engineering mix of design for testability, test view creation, and verification. This mixture facilitated timely test generation and had other important benefits. We d

Point defects, which cause small current increases and potentially early failures, can be masked by increased chip background currents at elevated temperatures. The difficulty of screening point defects will likely also occur in denser geometries. De

Parallel signature analyzers (PSAs) implemented as multiple input linear feedback shift registers are very useful in compressing test response data in digital circuits. In this paper, some analytical results on error detection using a class of PSAs a
