Test data compression has been an effective way to reduce test data volume and test time
as well as to solve automatic test equipment (ATE) memory and bandwidth limitation. We analyze the limitations of current test data compression algorithm and draw on the previous experience to deduce an optimal compression coding model suitable for SoC test data. In addition
in this paper we make full use of the relevance of the test vectors and the advantages of statistical coding to present an efficient test data compression method RLE-G based on the coding model
and give the RLE-G the optimal compression efficiency of the boundary conditions and realization steps. The experimental results for ISCAS 89 benchmark circuits demonstrate RLE-G have the excellent advantages of high compression ratio. (2010) Trans Tech Publications.

We investigated electro-optic modulator structures to target low drive voltage
high-speed modulation
and small device size with c-axis grown BaTiO3/MgO ferro-electric thin films. In this study
the calculations are focused on the ideal thin film with a quadratic relation between the half-wave drive voltage V and the interaction length L in the electro-optic modulation case we obtained in previous work. With the quadratic electro-optic modulating relation and the optimal rib waveguide structure of BaTiO3/MgO thin films
the frequency-voltage-size performances for 2.5GHz
10GHz
40GHz
and 100GHz modulation bandwidths have been obtained under half-wave drive voltages of 0.8V
1.6V
3.0V and 4.8V
respectively
for the ideal film with r51=730 pm/V at 1550nm wavelength
where both the phase velocity matching condition and the conductor induced microwave attenuation are considered. The required device lengths to achieve these four typical values of modulation bandwidth are 3.3 mm
0.8 mm
0.4 mm and 0.2 mm
respectively. With the c-axis grown BaTiO3/MgO crystal thin films and the quadratic electro-optic modulating relation
an electro-optic coefficient of reff=180 pm/V for the c-axis grown BaTiO3/MgO ferro-electric thin films was measured
which is relatively far from the ideal value of r51=560 pm/V. copyright The Electrochemical Society.
