Abstract:
1. Method for simulating an electronic circuit, represented in the form of masks and connections, comprising: a) the definition of the circuit in the form of a first list of electrical components and their inter-connections, b) the separation of the data from this first list into a first sub-assembly of components to be modified by a filtering step, and into a second sub-assembly of components not to be modified by said filtering step, c) the filtering of the data from the first sub-assembly of components, d) the definition of the circuit in the form of a second list of electrical components and their inter-connections, from the data from the second sub-assembly and from the data resulting from step c), e) the simulation of the circuit by means of said second list by using a computer, and f) in case of satisfactory result of the simulation, the production of the circuit, wherein the filtering step c) comprises a step of filtering the values from a symmetric matrix preserving its positive definiteness, and wherein: 1) two error parameters are defined: 2) for any element C where Ωpq is a rotation matrix on the indices (p, q): where: c=cos Θ and s=sin Θ, the value of the angle Θ being chosen so as to have: 3) if, for all of the non-diagonal elements (thus i≠j) of C′ and C: 4) if not, the matrix C remains unchanged.
