We formulate a behavioral model order reduction approach for nonlinear circuits based on the canonical Hammerstein architecture. The work extends the ideas of [1] to arbitrary loads and improves the efficiency of the model inference by training the linear time invariant (LTI) block in the frequency domain. We demonstrate the approach with an LM741 operational amplifier and present simulation results showing its application over a range of input frequencies and loads.

This paper presents a rational approach to construct thermal circuit networks equivalent to a discretization of the heat equation by the Finite Element Method (FEM). After the derivation of FEM-based thermal circuit networks, modelreduction techniques are further applied to derive reduced thermal circuit networks for the efficient electro-thermal simulation of power electronic circuits and devices in the circuit simulators.

This paper considers the advantages of statistically motivated reasoning in analyzing the nonlinear modelreduction problem. By adopting an information-theoretic analysis, we argue that the general analog macromodeling is tractable on average by nonlinear reduction methods. We provide examples to illustrate the importance of utilizing prior information, and provide a general outline of algorithms based on reproducing kernel Hilbert space machinery.

Reduced basis methods are popular for approximately solving large and complex systems of differential equations. However, conventional reduced basis methods do not generally preserve conservation laws and symmetries of the full order model. Here, we present an approach for reduced model construction, that preserves the symplectic symmetry of dissipative Hamiltonian systems. The method constructs a closed reduced Hamiltonian system by coupling the full model with a canonical heat bath. This allows the reduced system to be integrated with a symplectic integrator, resulting in a correct dissipation of energy, preservation of the total energy and, ultimately, it helps conserving the stability of the solution. Accuracy and stability of the method are illustrated through the numerical simulation of the dissipative wave equation and a port-Hamiltonian model of an electric circuit.

This paper presents a new open-source simulator that aims to provide a tool to study a wide range of current and future problems requiring high-resolution distributed simulation in engineering practice, especially in microelectronics. The problem to be studied is defined as a circuitmodel, which can be specified by a SPICE-like description. The simulator solves this circuit using the highly efficient Successive Network reduction Method, optimized specifically for solving circuitmodels of fields discretized by the Finite Differences or Finite Volumes methods. The circuits can be extended with programmable special components: controllers, to easily implement special tasks such as hysteresis or ray tracing modelling.
