A method for specifying characteristics of an integrated circuit wherein complementary output signals of the integrated circuit are required to cross or equal one another within a signal transition box during transitions of the complementary output signals. The signal transition box is defined by a maximum output signal level as a high side, a minimum output signal level as a low side, a minimum delay time as a leading side and a maximum delay time as a trailing side. A maximum allowable slew rate preferably is also defined.
