Beispiel hierf{\"u}r sind CVTGetriebe. Die ersten Getriebe dieser Bauart waren
weitgehend mechanisch/hydraulische Strukturen [1]. Modernere CVT-Getriebe, wie

Entwicklungsphasen diskutiert werden, da namentlich die Konzeptphase durch die

external test chip and the circuit under test. The hardware costs on chip are
significantly lower compared with a deterministic BIST scheme while the test

Deterministic Logic BIST (DLBIST) architecture. We consider several DLBIST
implementation options that result in test sequences of different lengths.
Resistive bridging faults are used as a surrogate of non-target defects.
Experimental data obtained for largest ISCAS benchmarks suggests that, although
DLBIST always guarantees complete stuck-at coverage, test sequence length does
influence the non-target defect detection capabilities. For circuits with a
large fraction of random-pattern resistant faults, the embedded deterministic
patterns as well as a sufficient amount of random patterns are both
demonstrated to be essential for non-target defect detection. It turns out,
moreover, that area cost is lower for DLBIST solutions with longer test
sequences, due to additional degrees of freedom for the embedding procedure and
a lower number of faults undetected by pseudorandom patterns. This implies that
DLBIST is particularly effective in covering non-target defects.}, url = {http://www2.informatik.uni-stuttgart.de/cgi-bin/NCSTRL/NCSTRL_view.pl?id=INPROC-2005-116&engl=0} }

requirements on test volume, test application time, test speed, and test
resolution. To overcome these challenges, it is widely accepted to partition
test resources between the automatic test equipment (ATE) and the circuit under
test (CUT). These strategies may reach from simple test data
compression/decompression schemes to implementing a complete built-in
self-test. Very often these schemes come with reduced diagnostic resolution. In
this paper, an overview is given on techniques for embedding test into a
circuit while still keeping diagnostic capabilities. Built-in diagnosis
techniques may be used after manufacturing, for chip characterization and field
return analysis, and even for rapid prototyping.}, url = {http://www2.informatik.uni-stuttgart.de/cgi-bin/NCSTRL/NCSTRL_view.pl?id=INPROC-2005-115&engl=0} }

desktop applications. For embedded systems development, usage of open source
software can also reduce development and licensing costs. We report on our
experience in developing a Systemon- a-Chip (SoC) audio player using various
open source components in both hardware and software parts as well as in the
development process. The Ogg Vorbis audio decoder targeted for limited
computing resource and low power consumption devices was developed on the free
LEON SoC platform, which features SPARC-V8 architecture compatible processor
and AMBA bus. The decoder runs on the open source RTEMS operating system making
use of the royalty-free open source Vorbis library. We also aim to illustrate
the use of hardware/software co-design techniques. Therefore, in order to speed
up the decoding process, after an analysis, a computing-intensive part of the
decoding algorithm was selected and designed as an AMBA compatible hardware
core. The demonstration prototype was built on the XESS XSV-800 prototyping
board using GNU/Linux workstations as development workstations. This project
shows that development of SoC using open source platform is viable and might be
the preferred choice in the future.}, url = {http://www2.informatik.uni-stuttgart.de/cgi-bin/NCSTRL/NCSTRL_view.pl?id=INPROC-2005-114&engl=0} }

SRAM cells. Reliability evaluation is an important step in designing highly

marketplace. This paper proposes a mathematical model able to evaluate and
