Common methods of testing physical design algorithms and functional verifications used today rely on standardised sets of widely accepted benchmark circuits, or on generating a random benchmark circuit based on its desired characteristics. Although these approaches are suitable in many situations, sometimes it is advantageous to know an exact function of a benchmark circuit. This article introduces a new method for generating benchmarks that is based on structural modifications of a user-specified design without altering its function. The method uses a set of pre-defined operations on a circuit netlist. The method is demonstrated on several examples.","PeriodicalId":180690,"journal":{"name":"Proceedings of the 12th IEEE International Conference on Fuzzy Systems (Cat.

The incorrect function of a given combinational circuit has to be detected and signalized at the time of its appearance and before its further distribution. It means that a safe operation is guaranteed. The ability to detect an error without stopping circuit function is called concurrent error detection (CED). We have used combinational circuits only to simplify testing process. A previous research was based on benchmarks described by tables. In some cases benchmarks with many inputs cannot be described by tables easily. The benchmarks used in our experiments to compute a quality of the code are described by equations. All of them will be implemented in XILINX FPGA circuits. Therefore the fault model considers the way of configuration data storage in memory. This work is a part of a more complex methodology of fault tolerant design based on FPGAs with a possibility to reconfigure the faulty part of the circuit.","PeriodicalId":180690,"journal":{"name":"Proceedings of the 12th IEEE International Conference on Fuzzy Systems (Cat.

The 16-bit THUMB ISA from ARM Ltd has a significantly higher density than the original 32-bits ARM ISA. In this paper we propose a new memory compression architecture, which employs a lossless data compression algorithm to achieve a further size reduction of around 20% on the THUMB code. We show that in some applications, the decompression can be performed in software on the main system processor without excessive processing time overheads.","PeriodicalId":180690,"journal":{"name":"Proceedings of the 12th IEEE International Conference on Fuzzy Systems (Cat.

The collector-tub is realized by etching the buried oxide (BOX) at the collector high-low (NN/sup +/) junction side followed by an N-implantation in a conventional lateral bipolar transistor (LBT) on SOI. Such a modification makes the collector potential to be absorbed both by the collector drift and substrate regions and the electric field spreads along the collector drift length. The simulation results show that by choosing appropriate buried oxide (BOX) thickness (t/sub OX/), collector-tub junction depth (X/sub j/), drift region doping (N/sub D/) and substrate doping (N/sub S/), the electric field profile in the collector drift region of the CTLBT can be redistributed so that its BV/sub CEO/ value is more than double when compared with a conventional lateral bipolar transistor on SOI. The reasons for this significant improvement in breakdown performance are explained.","PeriodicalId":180690,"journal":{"name":"Proceedings of the 12th IEEE International Conference on Fuzzy Systems (Cat.

The technique is relatively simple based on (1) internal capacitances of CMOS current mirrors and (2) a resistor of a CMOS current mirror for a negative resistance. No external capacitances or inductances are required. As a particular example, a 3.02-GHz, 0.4-f/sub T/, 0.31-mW, CMOS sinusoidal quadrature oscillator has been demonstrated. The oscillation frequency (f/sub 0/) is 3.02 GHz. The ratio of (f/sub 0//f/sub T/) is 0.4. The power consumption is low at approximately 0.31 mW. Total harmonic distortions (THD) are less than 0.3%. The oscillation frequency is current-tunable over a range of 660 MHz or 21.85%. The amplitude matching and the quadrature phase matching are better than 0.029 dB and 0.15/spl deg/, respectively. A figure of merit called CNR/sub norm/ is 161.68 dBc/Hz at the 2 MHz offset from 3.02 GHz.
