Abstract
A computer-implemented method is disclosed for adjusting impedance. A list of differential line pairs in a circuit design database is searched through for a target differential line pair, where the target differential line pair is flagged as having an incorrect characteristic impedance. A position in a circuit layout described in said circuit design database of at least one line in the differential line pair is adjusted to correct the characteristic impedance.
