SUMMARY OF THE INVENTION To achieve the above object, the present invention provides a semiconductor design graphical user interface device incorporating a second pointing function such as a wheel or lever.

[0011]

Embodiments of the present invention will be described below.

FIG. 1 shows a semiconductor layout display device incorporating a mouse capable of indicating the amount of rotation.

The mouse 101 is a mouse having a wheel 102 as a second pointing function. The wheel is triggered according to a certain amount of rotation, and changes accordingly. For example, 1/4 rotation
In the following description, it is assumed that an operation such as one change, two rotations, two rotations, and two rotations in the opposite direction, -2 change, can be performed.

FIG. 2 shows a mouse incorporating a plurality of wheels.

The mouse 201 has, in addition to the second pointing function, third, fourth, and fifth pointing devices. For example, the coordinates are up, down, left, and right. This is for indicating or changing a plurality of factors. Another way to address multiple factors is to:
There is also a method by combining with keyboard input. For example, in combination with the input of the keyboard 104 of FIG.
When the pointing function is operated, the factor can be changed by making another change. In addition, a plurality of factors can be dealt with by changing the change content of the component depending on the location of the component.

FIG. 9 shows a flowchart according to the present invention.

The mouse pointer on the drawing is moved by the first pointing function, the contents operated by the second, third, and fourth pointing functions are switched according to the position, and the drawing, wiring, and cells are switched and changed. Is what you are trying to do. In the following, an example of the modification will be described in detail.

FIG. 3 shows the switching of the drawing for each logic, arrangement, wiring or wiring layer.

The display device has a logic diagram 303.
Is displayed. When the wheel rotates in the direction A, the floor plan drawing 304 is displayed. Further, according to the number of rotations in the direction A, the layout drawing 305, the wiring drawing 1, the wiring drawing 2,... So that it can be switched to Further, when the wheel 302 is rotated in the direction B, the direction is changed in the direction opposite to the direction in which the drawing is changed in the direction A, and the drawings can be easily switched.

According to this embodiment, the drawing can be changed without moving the mouse pointer for the cell or wiring pattern to be corrected. This operation is especially effective when wiring across layers, and you can switch the layer to be displayed or edited while hovering the mouse cursor on the wiring being routed, making it easy to add or modify wiring it can.

FIG. 4 shows an embodiment in which the floor plan is enlarged, and FIG. 5 shows an embodiment in which the floor plan is enlarged and there is a displayed object, and the display location is changed.

Here, there are a plurality of scales, coordinates, and change factors, and it is difficult to determine the change factor with only one wheel. Therefore, by using a mouse having a plurality of wheels, it is possible to cope with a plurality of factors. For example, FIG.
An input device having a plurality of wheels as shown in FIG. 4 uses a wheel 205 on a reduced scale and wheels 202 and 204 for moving coordinates.

The position to be enlarged is selected according to the position of the mouse pointer. When the wheel is rotated in the direction A, the position is enlarged, and when the wheel is rotated in the direction B, the position is reduced. When the wheel is rotated in the C direction, it moves upward, when the wheel is rotated in the D direction, it moves downward, and when it is rotated in the G direction, it moves in the left direction and H direction. If so, move to the right.

According to this embodiment, it is possible to scale up and down little by little, so that it is possible to scale up and down without losing a target and to move according to the amount of rotation of the wheel. It is possible to perform a display without too much.

FIG. 6 shows a cell displayed.

A cell has a plurality of cell widths, characteristics, coordinates, and change factors, and it is difficult to determine a change factor using only one wheel. Therefore, by using a mouse having a plurality of wheels, it is possible to cope with a plurality of factors. For example, an input device having a plurality of wheels as shown in FIG.
Wheel 202 for moving the cell left and right, wheel 204 for moving the cell up and down, wheel 203 for changing the cell size,
205 is used to change the characteristics of the cell. For example, cell 60
By selecting 1 and rotating the wheel 202,
The cell is moved according to the number of rotations. By rotating the wheel 204 after selecting the cell 602, the cell width according to the number of rotations is changed.

According to this embodiment, the location and size can be changed in accordance with the amount of rotation of the wheel, so that an operation without excessive change can be performed.

FIG. 7 shows a part of the wiring pattern.

Also in the case of wiring, there are a plurality of change factors with the layer, width, coordinates, and it is difficult to determine the change factor with only one wheel. Therefore, by using a mouse having a plurality of wheels, it is possible to cope with a plurality of factors. For example, an input device having a plurality of wheels as shown in FIG.
When changing the wiring, a plurality of factors can be changed by changing the wiring width with the wheel 205, the wiring layer with the wheel 203, and the coordinates with the wheels 204 and 202. For example, with respect to 702, when reducing the wiring width,
Rotate the wheel in direction A to increase the wiring width B
Rotate in the direction. When the wiring coordinates of the wiring pattern 704 are shifted up and down, wheels C and D are used.

Next, a description will be given of an embodiment in which unwired wires are manually wired.

In FIG. 8, terminals 801 and 802 are provided.
Indicates a state in which wiring has not been performed because automatic wiring could not be performed.

First, by operating the mouse to move the mouse pointer to the terminal 801 and clicking a predetermined button of the mouse, wiring is started. In this state, the layer and the width can be selected by operating the wheel. When the mouse pointer is moved to the relay point 803 and a predetermined button of the mouse is clicked, the pattern up to the relay point ends. Thereafter, when wiring is performed in the Y direction, the layer and width can be selected by operating the wheel. After selecting the layer and width, move the mouse pointer to the terminal 802 and click a predetermined button of the mouse to complete the wiring manually with no wiring.

According to this embodiment, it is possible to change the layer or width to be wired next without moving the mouse pointer at the relay point. This is especially effective when there are many relay points.

According to this embodiment, the cell or the wiring pattern to be corrected can be changed without moving the mouse pointer, and can be easily corrected.

[0035]

As described above, according to the present invention, it is possible to smoothly switch the display of logic, arrangement, and wiring.
