Abstract:
A method for determining an oscillating region of an electrical circuit comprising at least one oscillator and additional structural elements connected to the oscillator, the method comprising the steps of:in a computing device, executing, in an iterative method, upon variation of combinations of circuit parameters of the additional structural elements, the following steps for each instance of the circuit parameters:performing a stability analysis of said electrical circuit for a respective instance for determining whether said instance oscillates;if the analyzed instance oscillates, assigning said instance a first value in a matrix in which all parameter combinations being analyzed are stored, said first value indicating that said instance oscillates;if the analyzed instance does not oscillate, assigning said instance a second value in the matrix, said second value indicating that said instance does not oscillate; andderiving the oscillating region from said parameter combinations that have been assigned said first value in said matrix.
