The study targets the development of a SoC platform for the design of next generation network processing. Circuits with an 8-bit, 16-bit, 32-bit and a 64-bit data-path have been implemented and analysed in terms of, scalability, hardware cost, speed, and data throughput capabilities. The circuit analysis is based on performance results with the UMC 0.18 /spl mu/m standard cell libraries obtained using Synopsys physical compiler. Analysis shows that the 64-bit datapath architecture is able to achieve data rates beyond l0Gbps whereas the 8-bit data-path architecture is very compact and operates with a clock rate of close to 300MHz. Considering the throughput-rate versus silicon area cost as a measure of silicon area efficiency, then the 16-bit data-path architecture proves to be the most efficient.","PeriodicalId":184894,"journal":{"name":"IEEE International SOC Conference, 2004.

The local bitline shares a sleep transistor for aggressive bitline leakage reduction/tolerance to enable high fanin bitlines and uses low V/sub th/ transistors. The sleep transistor is turned on while accessing the local bitline and conditionally turned off, if the dynamic node should remain high. Simulation results shows that proposed technique achieves 9% improvement in performance with 14/spl times/ reduction in local bitline leakage (97/spl times/ reduction as compared to any previously proposed low V/sub th/, leakage tolerant register file) enabling 70% reduction in keeper size, while keeping the same noise robustness as optimized high performance conventional high V/sub th/ implementation.","PeriodicalId":184894,"journal":{"name":"IEEE International SOC Conference, 2004.

The BIST circuitry consists of a pattern generator and detector, a signal comparator and a high-pass filter. It outputs an error indicator that is used as a control signal in the adaptive pre-emphasis block. The feedback loop inherent in a simultaneous bidirectional link provides a natural opportunity to carry information about the channel characteristics without the need for an extra dedicated wire. The design has been verified using the Cadence SpectreRF and Verilog-A simulators and the channel loss characteristics are based on an FR-4 material model extracted from the Cadence Transmission Line Model Generator.","PeriodicalId":184894,"journal":{"name":"IEEE International SOC Conference, 2004.

The DFE adapts to the channel impulse response by observing a calibration sequence sent across the channel. Uninterrupted signaling is maintained across a parallel bus by providing an additional channel and using multiplexors to reroute the signals of the channel being calibrated. Using the intermittent calibration sequence instead of the conventional LMS adaptation technique removes the need to generate an error signal, eliminating the associated analog blocks. Also presented is a novel method of using the DFE adaptation circuits to extract the system's pulse response. The complete transceiver is implemented in a 0.18 /spl mu/m CMOS process.","PeriodicalId":184894,"journal":{"name":"IEEE International SOC Conference, 2004.

The basis for the methodology is the use of the model compiler that allows one to compile models written in high-level behavioral description language and make them available to a standard circuit simulator. For demonstration purposes, we consider two mixed-technology examples: an optoelectronic example (a laser diode circuit) and a thermo-electronic example (thermally coupled MOS inverter). We use model compiler MCAST developed in our group to compile VHDL-AMS models and make them available to SPICE circuit simulator. Our results demonstrate that model compiler technology allows one to perform simulation of mixed-technology systems in a circuit simulator. The methodology described here is general and can be used with various model compilers and circuit simulators, as long as good mathematical models for mixed-technology devices are available.","PeriodicalId":184894,"journal":{"name":"IEEE International SOC Conference, 2004.

Due to technology scaling and reduced supply voltages, they are expected to increase by several orders of magnitude in logic circuits in the near future. Existing circuit and architectural solutions are inadequate because they have appreciable area/cost, performance, and/or power overheads. We present a very efficient and systematic error-masking technique for static CMOS combinational circuits that prevents an SET pulse, with width, in the worst case, less than approximately half of the timing slack available in its propagation path, from latching and turning into a soft error. The SET is masked without additional delay and within the clock cycle time in an area-efficient manner, which makes this technique applicable to commodity as well as reliability-critical applications. Application of this technique to ISCAS85 benchmark circuits yields average soft-error rate reduction of 75.71% with average area overhead of only 18.14%.","PeriodicalId":184894,"journal":{"name":"IEEE International SOC Conference, 2004.
