Abstract: A method for defining an area of a computer screen (10). The defined area is specified as box (15) which the user may rigidly move vertically and horizontally and adjust both the width and height of the box (15). A single keystroke and motion of a mouse is sufficient to define the box (15), to resize the box (15) and to rigidly move the box (15).

Abstract: A method for obtaining characterization of timing parameters of a sequential circuit includes inputting predetermined data sequences to the sequential circuit. The sequential circuit is then simulated in response to the predetermined data sequences, and signals appearing at internal nodes of the sequential circuit are observed with respect to time. A plurality of timing parameters of the sequential circuit can then be calculated by using the values of the signals at the internal nodes.
