Abstract

A computer program is disclosed for use in the computer-assisted design of an integrated circuit, to carry out the function of translating a rectangular shape from a first position to a second position which is a precise given distance from a first reference point. Figs. 1 and 2 illustrate the sequence of steps in the program, and Fig. 3 is a flow diagram of the program.

Set Reference for a Move of a Shape

A computer program is disclosed for use in the computer-assisted design of an integrated circuit, to carry out the function of translating a rectangular shape from a first position to a second position which is a precise given distance from a first reference point. Figs. 1 and 2 illustrate the sequence of steps in the program, and Fig. 3 is a flow diagram of the program.

The program presented allows the fast accurate placement of a graphics shape relative to any point on the display. The hardware/ software system used is a graphics design system, the prior art consisting of identifying a shape and then moving it by trial and error until it is in the correct position. The invention disclosed here represents a considerable improvement in productivity for the editing of existing structures.

The invention works by leading the user through the sequence of steps which follow and which are illustrated in Figs. 1 and 2: 1) Select shape to be moved 2) Select reference point 3) Enter delta X, delta Y 4) Select corner of shape to be moved 5) Repeat, as desired, with different shapes

This sequence represents the minimum number of steps required to relocate a graphics shape to a precisely defined location which is relative to a selected point.

Referring to the flow diagram of Fig. 3, the program is initialized by selecting it in block 1. Block 2 prompts the user to detect on a shape which is to be moved. Block 3 prompts the user to detect o...
