A method for analyzing circuit comprises the steps of selecting a plurality of elements; sampling the selected elements, resulting in a plurality of sampling-parameter sets; simulating the sampling-parameter sets to generate a plurality of simulation-results, and process the regression operation for the sampling-parameter sets and simulation-results in order to acquire the contribution rank of each sampling-parameter set and element. Accordingly, while analyzing similar circuits, the partial elements can be selected according to the contribution rank and further sampled; thereby, the amount of sampling-parameter sets can be advantageously reduced, and the analysis efficiency can be improved according to the circuit.
