Abstract: Simulation of electromagnetic characteristics of an electrical circuit uses netlist data defining component instances, including layout component instances, and their topological interconnection in an electrical circuit. A circuit simulation is performed using the netlist data, involving use of a model for each layout component instance. An attempt is made to retrieve an existing simulation model of the layout component instance from a database of such layout component simulation models. If no suitable simulation model can be found in the database, an attempt is made to interpolate a new simulation model from among existing simulation models in the database. If interpolation is determined not to be feasible, then an electromagnetic simulation of the layout component instance is performed to develop a new electromagnetic simulation model. This new model is used in the circuit simulation, and added to the database for future use.

Abstract: Call detail records are generated for usage of a telecommunications service established in a telecommunications network, by monitoring messages in a signalling system for co-ordinating operation of the network and carried over signalling links in the signalling system between a service switching function entity and a service control function entity.

Abstract: A development environment includes a graphical design tool and a build agent. The graphical design tool allows a designer to design a primary logic component of a circuit. The graphical design tool generates modules using a hardware description language to represent the primary logic component of the circuit.

The build agent synthesizes the modules into netlists and merges the netlists with a description of the infrastructure for the circuit. The infrastructure is generated in a development environment separate from the graphical design tool. The build agent includes an adjuster that adjusts the modules. The adjustment to the modules includes replacing the abstract references to the infrastructure with actual references utilized within the infrastructure.

Abstract: Low intensity light is incident upon a photodiode whose output is coupled to an integrator. The output of the integrator is coupled to an input of an A/D converter, whose output is coupled to a microprocessor, whose output is coupled to a filter. A second output of the microprocessor is coupled to a gate electrode of a FET to provide a reset signal to the FET to reset the integrator. The microprocessor compares the digital samples of the integrated signal from the A/D converter and, firstly, generates the reset signal if a sample is beyond a set limit, and, secondly, calculates delta values between adjacent samples and interpolates the delta values for the reset periods so as to provide a continuous data stream which can be filtered by a filter matched to the form of the original signal.
