A method for predicting risk and designing safety management systems of complex production and process systems which has been applied to an FPSO System operating in deep waters. The methods for the design were derived from the inclusion of a weight index in a fuzzy class belief variable in the risk model to assign the relative numerical value or importance a safety device or system has contain a risk hazards within the barrier. The weights index distributes the relative importance of risk events in series or parallel in several interactive risk and safety device systems. The fault tree, the FMECA and the Bow Tie now contains weights in fizzy belief class for implementing safety management programs critical to the process systems. The techniques uses the results of neural networks derived from fuzzy belief systems of weight index to implement the safety design systems thereby limiting use of experienced procedures and benchmarks. The weight index incorporate Safety Factors sets SFri {0, 0.1, 0.2 . . . 1}, and Markov Chain Network to allow the possibility of evaluating the impact of different risks or reliability of multifunctional systems in transient state process. The application of this technique and results of simulation to typical FPSO / Riser systems has been discussed in this invention.

Coding within noisy communications channels is essential but a theoretical maximum rate defines the rate at which information can be reliably transmitted on this noisy channel. Capacity-achieving codes with an explicit construction eluded researchers until polar codes were proposed. However, whilst asymptotically reaching channel capacity these require increasing code lengths, and hence increasingly complex hardware implementations. It would be beneficial to address architectures and decoding processes to reduce polar code decoder complexity both in terms of the number of processing elements required, but also the number of memory elements and the number of steps required to decode a codeword. Beneficially architectures and design methodologies established by the inventors address such issues whilst reducing overall complexity as well as providing methodologies for adjusting decoder design based upon requirements including, but not limited to, cost (e.g. through die area) and speed (e.g. through latency, number of cycles, number of elements etc).

To a cell library pattern which makes the basic constitution of a semiconductor circuit pattern, OPC processing is performed beforehand, and a semiconductor chip is produced using this cell library pattern. Since it is influenced by the pattern of the cell arranged to the circumference and the pattern arranged around other cells at this time, correction processing (optimization processing) is performed. The part of this correction processing is a portion in which a pattern faces between cell boundaries in the inside of the region specified from the cell boundary, and proximity effect correction is performed by making the width, the length, and the position of this portion into variables. Or proximity effect correction is performed by making a polygon into a variable. Or sizing is done and proximity effect correction is performed.

A Digital Design Method which may be automated is for obtaining timing closure in the design of large, complex, high-performance digital integrated circuits. The methodincludes the use of a tuner on random logic macros that adjusts transistor sizes in a continuous domain. To accommodate this tuning, logic gates are mapped to parameterized cells for the tuning and then back to fixed gates after the tuning. Tuning is constrained in such a way as to minimize “binning errors” when the design is mapped back to fixed cells. Further, the critical sections of the circuit are marked in order to make the optimization more effective and to fit within the problem-size constraints of the tuner. A specially formulated objective function is employed during the tuning to promote faster global timing convergence, despite possibly incorrect initial timing budgets. The specially formulated objective function targets all paths that are failing timing, with appropriate weighting, rather than just targeting the most critical path. Finally, the addition of multiple threshold voltage gates allows for increased performance while limiting leakage power.

There is no conventional method for precisely estimating under what external conditions each partial circuit, such as a library cell, is utilized in an actual integrated circuit at the time of designing the partial circuit. Therefore, by estimating the external conditions of a partial circuit when used in an integrated circuit so that the partial circuit is designed in accordance with the external conditions, the partial circuit having optimal performance for the external conditions can be designed. The step of external condition estimation can be formed so as to include the technology conversion step which technologically converts the layout for external condition extraction, that is prepared in advance, based on the technology information of an integrated circuit, which is the design objective; the layout extraction step of extracting layout extraction information which is external information influencing the operation of the partial circuit from the layout for external condition extraction that has been technologically converted; and the external condition calculation step of calculating external conditions of the partial circuit from the layout extraction information. In addition, by simply replacing the designed partial circuit with a partial circuit of a circuit for evaluation, the evaluation of the designed partial circuit can be easily carried out.

An imaginary object plane is set in front of an imaging device body (plane setting step). A part of optical conditions of optical lenses are changed as variables, and positions of points (pixel observation points) on the imaginary object plane where lights coming from pixels of a solid-state imaging element and back-projected through the optical lenses are calculated (pixel observation point calculating step). The dispersion in position of the calculated pixel observation points is evaluated (evaluating step). Finally, a set of values of the variables giving maximum evaluated dispersion of the calculated pixel observation points is determined as optimum optical condition of the optical lenses (condition determining step). This reduces the number of pixels which image the same portions of the target object, making it possible to reduce portions of the same image information in multiple unit images, and to stably obtain a reconstructed image having a high definition.

A closed-loop IC design optimization process by automatically or manually creating design-specific cells with desired characteristics (e.g., performance, area, power, noise, etc.), which will be then implemented as a standard cell (also known hereafter as metacell), from a set of post-layout patterns. A post-layout pattern represents a part or whole of a standard cell and contains information regarding the pattern including, but not limited to, layout, timing, area, power and noise. As the metacells are created from post-layout patterns, the inaccuracies of prior dynamic library techniques are easily avoided. Such metacells, being design-specific, are optimized to satisfy the constraints imposed by the design context, thus bringing the powerful design-specific customization to standard cell-based design methodology.

The customized processor normally executes a sequence of a plurality of pre-customized routines, usually for which it has been optimized. To provide some flexibility for design changes and optimizations, a controller for monitoring the customized processor during execution of routines is provided to select one of a set of pre-customized processing interruption points and for switching context from the customized processor to the flexible processor at the interruption point. The customized processor can then be switched off and the flexible processor carries out a modified routine. By using sharable a data store, the context switch can be chosen at a time when all relevant data is in the sharable data store. This means that the flexible processor can pick up the modified processing cleanly. After the modified processing the flexible processor writes back new data into the data store and the customized processor can continue processing either where it left off or may skip a certain number of cycles as instructed by the flexible processor, before beginning processing of the new data.
