Abstract

PURPOSE:To easily design a layout by adding a light pen for graphic input and a large-size graphic display device to a work station. CONSTITUTION:A memory means 13 stores the basic software for command processing, etc., the knowledge data base and the graphic processing procedure. For instance, a designer is going to draw a square on a picture and indicates 19 the input of a square out of an input selection table shown on the picture by means of a light pen 2. Then four apexes serving as desired parameters are supplied 20 by the pen 2 on the screen. A work station judges 21 whether an input pattern is appropriate or not. And displays 22 the reason and the position of an error if detected.

Description

DETAILED DESCRIPTION OF THE INVENTION (“Industrial Application Field”) The present invention relates to an integrated circuit pattern (hereinafter referred to as layout) design device, and particularly relates to a large-scale integrated circuit (hereinafter referred to as LSI) design device.
This is related to layout design C2.

[Conventional technology]

FIG. 2 is an overall view of a conventional workstation. Character display device (3), graphic display device (11), keyboard (4) for inputting commands for inputting coordinates and editing/correcting figures, electronic coordinate input board (6: hereinafter referred to as tablet) It is equipped with an electronic pen ((7), hereinafter referred to as a stylus pen) for specifying a coordinate position on a tablet and inputting the coordinate value, and is connected to a central computer (51).

Next, the operation will be explained. The designer wrote the layout, temperature and humidity (- so it changes depending on the temperature and humidity).He placed a sheet of mylar paper on the tablet and moved the stylus pen to the target coordinate position.
The figure display device displays grid points corresponding to the intersections of the grid marks on the Mylar paper (hereinafter referred to as grid points). The input graphical information is sent to the central computer and stored on magnetic tape (hereinafter referred to as digitization). Figure 3 shows the flowchart up to digitization. Conventionally, workstations are used at the αυ stage, and +81, (
Since the work of 9+ and σU is done by humans, there are problems such as it is time consuming, it is easy to overlook errors, and two sheets of mylar paper are required.

This invention was made in order to solve the above-mentioned problems, and provides a device that allows a designer to directly design a layout on the screen and also automatically checks design standards while designing. The purpose is to

[Means for solving problems]

This output qC-related workstation has a graphic input pen (
It is equipped with a large graphic display device (hereinafter referred to as a light pen), a built-in CPU, and software to realize a knowledge database and judgment function.

[Effect]

In this invention, a layout is designed by drawing a figure on the screen of a figure display device with a light pen, coordinate values of arbitrary points are input, and the input information is checked by the software.

〔Example〕

FIG. 1 shows an embodiment of the invention. 11+ is a graphic display device that is movable so that the designer can design in a comfortable position. The designer places the Nilight pen (2) on the screen of the graphic display device to design the layout. Attributes such as lines and color types used during design, commands for editing and modifying shapes are also displayed on the same screen, and the light pen (2
) Selecting them 1: Improve workability.

Correspondence from the workstation to the input information is displayed on the character display device (3) and is responded to by inputting a response command from the keyboard (4).

FIG. 4 is a block diagram of the inside of the workstation.

az is a CPU that processes graphic information and controls peripheral devices; (I3 is a storage device that stores basic software such as graphic processing and command processing and a knowledge database).

Based on the basic software, the CPU controls a communication device I for sending design data after completion of processing to the central computer (5) and a peripheral device control device that controls peripheral devices ((1) to (4)). .

FIG. 5 is a software configuration diagram, in which a core management program (151, hereinafter referred to as O8) manages the graphic processing program, the peripheral device control program (L?), and the knowledge database IEII.

Next, the function and operation of the embodiment will be explained. FIG. 6 is a flowchart of layout design. If a rectangle is to be drawn on the screen, the designer uses a light pen to instruct the input of a rectangle from the input selection table on the screen at αl. Next C! ■
Input the four vertices, which are the necessary parameters, on the screen using a light pen. The workstation then determines whether the input geometry is valid. If there is an error, the reason and location will be displayed on the character display device (22° If there are no errors or corrections are completed, wait for the next input (=).

〔Effect of the invention〕

As described above, according to the present invention, a light pen and a large graphic display device are combined, and the design and verification can be performed simultaneously on the screen through software processing, thereby shortening the development period and eliminating the need for Mylar paper. It has the effect of becoming
