摘要： The invention relates to a method for trimming an electronic system (200) in which n parameters (x, y) of the system (200) can be predetermined, which correspond to an n-dimensional trimming area, with two limit values (x0, XI y0, yl) being predetermined for each parameter (x, y) at the start of the trimming process, which limit values bound a corresponding output area (B_O) in the n-dimensional trimming area, and in which the following steps are repeated until a terminate condition is reached: - evaluation (100) of a target function which quantifies the reaching of a trimming target for the limit values (x0, xl, yϑ, yl), which bound the output area (B_O), with the evaluation comprising the measurement and/or evlauation of at least one physical variable of the system (200) which is dependent on the respective parameter (x, y) and/or its limit value (x0, xl, y0, yl), and with corresponding target function values associated with the limit values being obtained, - definition (110) of a changed, in particular reduced, output area (B_l, B_2) for a subsequent iteration as a function of the resultant target function values. According to the invention, the target function values are allocated to two different classes, with all the target function values which correspond to one target criterion being allocated to a first class, and with all the target function values which do not correspond to the target criterion being allocated to a second class, and with the changed output areas (B_l, B_2) being defined for the next iteration as a function of those target function values which are allocated to the first class.
