Cycle simulation is a well known method for high speed simulation. The technique of reducing master/slave latch pairs to single latches is also known, however, only if the master/slave latch pairs are used as defined. Today's highly optimized hardware designs use master/slave latches in such a general way, that a reduction to single latches has become a challenge. This paper shows a method to reach single latch models. General simulation problems of single latch models are also discussed.

A Unique CMOS Section Overhead (SOH) processor has been designed for use in 10 Gbit/s SDH-based optical transmission system. A uniquely structured chip makes it possible to use parallel processing of STM-64 SOH at low speed with four identical chips. The features supported by the chips include STM-64 SOH insertion and extraction including Regenerator Section Trace (RST), frame alignment word insertion, alarm detection and generation, and performance monitoring. This paper introduces a novel parallel circuit design methodology for processing STM-64 SOH and describes the unique architecture, implementation and experimental test results of the chip, SOH processor. This paper also presents the implementation methodology of RST using CRC-7 polynomial algorithm.

A crosstalk model that is both accurate and easily incorporated into an MCM router has been developed. This model accounts for coupling from multiple layers out to three wires in either direction and accounts for the shielding involved with those wires. An algorithm that calculates the effect of reflections from terminals with mismatched impedances is also included as part of the model. Finally,it is shown to be impractical to use a more complex crosstalk model without including some sort of timing simulator.

A sensor array consisting of MAGFETs and stochastic flip flop cells is proposed for the direct reading of magnetically stored information. A following adaptive filter provides the autocalibration of the flip flop cells by means of a biasing charge-pump and ensures the detection of the digital magnetic data for low over-sampling rates.

Layout verification has been proposed to improve the ESD (Electrostatic Discharge) and latchup immunity of scaled-down CMOS cell libraries. By using the DRC (design rules check) and ERC (electrical rules check), the ESD/latchup sensitive layout can be found. By changing the layout in the suggested way of high immunity to ESD and latchup without increasing the layout area of the cells, the ESD and latchup reliability of CMOS IC's assembled by the layout-verified cell libraries can be significantly improved.

This paper describes the challenges and indicates possible approaches in RF testing, focusing on digital systems, analog subsystems, and integrated mixed-signal systems. The approaches to innovative test techniques to reduce dependence on external automatic test equipment and to mitigate the analog test issues lead to a proposed integrated framework to serve as basis for future test developments. The interdependence between simulation and test is identified to support the framework and eliminate unnecessary test.

This paper describes the implementation of a complex image processing algorithm for a portable printer controller ASIC. The ASIC design and development process employs Synopsys's Behavioral Compiler as a new design methodology. This paper discusses the error diffusion image processing algorithm as an illustrative algorithm so as to better share the benefits and the difficulties when implementing such an algorithm using Behavioral Compiler.

K-band mixers are realised on GaAs MMIC technology by employing cold FET devices. With this submicrometer device, two configurations are studied and realized: the "series" and the "shunt". Experimental results are compared to theoretical predictions obtained on microwave nonlinear simulator by using an original modelling of the cold FET.

We discuss issues associated with system level access of Built-In Self-Test (BIST) for Field Programmable Gate Arrays (FPGAs) via the Boundary Scan Interface. In addition, we describe the design of an Application Specific Integrated Circuit (ASIC) which serves as an interface between a PC parallel port and the Test Access Port (TAP) of one or more FPGAs to reprogram the FPGA(s) and administer BIST during off-line testing. We also include a brief description of the FPGA BIST architecture and operation.

In image processing, moment-invariant is one of the most useful methods for feature extraction. However, real-time applications of this method have been prohibited due to the intensive computation required in calculating the moments of an image. This paper describes a hardware solution to this problem.
