The simulation of the passage of particles through matter using Monte Carlo methods is broadly used in the development of particle detectors for high energy physics experiments. To develop the readout electronics for the Compact Muon Solenoid (CMS) experiment at CERN, and to assist the design of the on-detector ASICs, a simulation framework was build capable to link the physics Monte Carlo simulations platforms with an industry standard EDA simulation tools. This contribution focuses on the implementation of the simulation framework based on the System Verilog language and the Universal Verification Methodology (UVM). The simulation results that guided the development of the ASICs and the choice of the final architecture are presented.

This paper presents the simulation comparison of two Interpolated DFT frequency estimation methods in the control of a renewable energy system. The first method uses four points of the spectrum in calculations and MSD (Maximum Sidelobe Decay) time windows and the second method uses three points of the spectrum and Generalized MSD time windows. simulations were performed for a modeled pure grid signal as well as signal distorted by Additive White Gaussian Noise and harmonic components in a very short estimation time. Both methods are very fast but the more accurate is the second method. The accuracy in real measurement conditions is in the order of 10(-4) Hz/Hz or 10(-3) Hz/Hz depending on the signal quality.

The paper demonstrates, how CAD design and simulation tools can assist in developing MEMS devices in general, and capacitive accelerometers in particular. Two types of surface-micromachined accelerometers are presented and described. Advantages and disadvantages of particular tools are discussed. The paper also includes sample simulation results, which prove that virtual simulations can provide the designer a lot of information with no need for device fabrication and measurements.

A novel model for power transformers design is presented in this paper. It is based on the use of two Geometric Form Factors (GFFs) - namely K-F and K-C - associated to magnetic cores shape and material. The transformer non-linear magneto-electro-thermal model is solved numerically to identify the commercial magnetic core whose GFFs allow minimizing the size of a custom transformer, under given power loss and thermal specifications. The model provides the boundaries of the acceptability region in the plane K-F-K-C enabling a straight comparison among multiple feasible solutions compliant with given design constraints. The case study presented in the paper concerns the design of a custom power transformer for an isolated DC-DC converter.

A numerical approach to model fatigue damage propagation in metal-on-silicon structures under transient thermal loading is presented. The considered fatigue failure mechanisms are fatigue crack growth inside the thick metallization and potential cyclic delamination growth at the interface between the metallization and the silicon. Advanced methods within the framework of the Finite Element Method are developed to study these failure mechanisms and to assess the material and interface degradation on a generic metal-onsilicon geometry. Such methodology can be applied to explore fatigue-determined robustness limits of power semiconductor devices exposed to severe temperature swings, e.g. during cyclic electric overload switching.

This paper deals with the design of a receiver for LTE band 20 consisting of microelectronic and MEMS-containing function blocks. It shows how multiphysical RF circuits can be considered in one design environment like Cadence Virtuoso. Finally, the simulation tool was extended by suitable models for used MEMS containing design parameters that are important for an electronics engineer. This unifies the design task and facilitates the evaluation of an implementation with and without MEMS by considering the entire receiver chain.

MATLAB/Simulink modeling of offset and flicker noise in Delta-Sigma modulators has been developed, providing a fast tool for the estimation of ADC performances. Since high accuracy and resolution are fundamental in sensor applications, a brief analysis of the main noise sources in second order Delta-Sigma modulators is presented, together with the typical solutions found in the literature. Generalization of system-level chopper technique for the rejection of the converter overall offset and low-frequency noise has been proposed and their effectiveness is evaluated by means of high-level simulations.

The sensitivity of integrated circuit parameters regarding manufacturing process variation represents a very important ongoing topic in the semiconductor industry. Establishing the functional relationship between them at an early stage, i.e. simulation, would create an advantage in terms of circuit improvement and eventually high production yield. This paper presents a methodology for finding the influence of technology parameters (i.e. Process Control Monitor parameters) on device performance. The methodology is based on Machine Learning algorithms and Bayesian Optimization framework with the purpose of modelling the functional dependencies between technology and circuit parameters. The experimental results prove that the device performance is highly sensitive to technology parameters variation and this dependency can be modelled.

This work reports on an universal lumped element model for integrated millimeter-wave (mmWave) transformers which is valid up to 100 GHz. The presented 2-pi architecture covers the calculation of planar and stacked transformer topologies as well as higher winding ratios and different geometries. All model components depend both on the transformer dimensions and technological parameters. A verification by electromagnetic field simulations in a 65 nm CMOS process results in a close agreement to the calculated S-parameter set.
