Abstract

In some embodiments, in a method for considering in-phase grouping for a voltage-dependent design rule, for a first net and a second net in a schematic, first data for obtaining the differences between first voltage values of the first and second nets, and between second voltage values of the first and second nets is provided. For each of the first and second nets, the first voltage value is larger than the second voltage value. A layout for the schematic is generated. In the layout, a relationship of a first shape and a second shape associated with the first and the second nets, respectively, is defined using the first data.
