Abstract:
1. A computer executable test point insertion method comprising: extracting, with at least one computer, a plurality of logic cones from a net list; generating an order for the plurality of logic cones based on a connection relation of logic cells in each of the plurality of logic cones; and setting a test point in each of the plurality of logic cones in turn in accordance with the order; wherein the order is generated based on a sum of the number of at least one path forming each of the plurality of logic cones and a sum of the number of logic stages of each of the at least one path; wherein the order is determined by a value generated by a following expression: wherein P (G) is a sum of the number of at least one path forming each of the plurality of logic cones, and P (L) is a sum of the number of logic stages of the at least one path, and α and β are preset coefficients.
