Systems and methods for determining a signal coupling coefficient for a line or trace in an electrical circuit layout are disclosed. The systems and methods include, for example, reading a threshold value for a signal coupling coefficient, identifying the line in a circuit design database, establishing a window around the line in which circuit elements will be included in a calculation of the signal coupling coefficient of the line, calculating a signal coupling coefficient of the line based upon the circuit elements in the window, flagging the line if the calculated coupling coefficient differs from the threshold value, flagging the target line with a design rule check if the threshold value exceeds the calculated coefficient and storing the design rule check in the circuit design database. Systems and methods for determining signal coupling coefficients for one or more vias or paths are also disclosed.
