Abstract
A computer-implemented method is disclosed for adjusting impedance of a differential via pair in an electrical circuit layout. A differential via pair having an odd mode characteristic impedance needing adjustment is identified in a circuit design database. A region is established around the differential via pair in which circuit elements may be modified to adjust the odd mode characteristic impedance of the differential via pair. At least one of the circuit elements in the electrical circuit layout in the established region is adjusted until the odd mode characteristic impedance is closer to a desired odd mode characteristic impedance value.
